rpc : use ggml logging facilities
Use RPC_DEBUG environment variable to enable debug messages.
Add helper macro LOG_DBG() which does an early
check of the env var before calling GGML_LOG_DEBUG().
Make sure we log a debug message for every server function.

ggml : split graph allocations according to backend max buffer size (#15815)
* ggml : make gallocr respect the backend's max buffer size

* if the graph requires more memory than can fit into a single allocation, split it into multiple backend buffers
* vulkan: report the actual max  allocation size in buffer type  interface

* fix missing newline, apple-clang warning

* track size of individual chunks in ggml_dyn_tallocr and raise max chunks.
revert to use suballocation_block_size as max chunk size for vulkan.

* track (chunk, offset) pairs instead of "global" offsets through gallocr.

* simpler, don't need loops to map between local/global offsets
* touches more code

* fix dyn_tallocr_max_size and initialization

* fix memory leak when buffers are reused due to same buffer type appearing multiple times

* make vbuffer allocation follow the same logic as backend_buffer did before

* continue to use leftover unallocated space of previous chunks after a new one has been created

* treat free blocks of each chunk as separate list
* they're still allocated together, but start/end of each chunk is tracked, and allocate/free iterate over sub-ranges
* exhaust freed blocks of all chunks before considering their last blocks with unallocated space
* start with 0 chunks/blocks and create chunks as needed
* allow the last chunk to grow beyond max size

* refactor: move adding new free block and new chunk into separate functions

* allocate chunks individually with a separate free-blocks list for each one

* needs a bit more memory/allocations/indirections, but code is simpler

* fix warnings (missing static) & debug checks

405921dcef ggml : introduce semantic versioning (ggml/1336)
* ggml : introduce semantic versioning

This commit introduces semantic versioning for the GGML library.

The motivation for this is that the current versioning, using build
numbers, makes it difficult to track changes and releases for projects
that use ggml.

The release steps are the following:
1. Sync the changes from llama.cpp using sync-llama-am.sh and after the
   PR has been approved and merged move to step 2.
2. Run scripts/release.sh and specify the type of release, major, minor,
   or patch. This script will handle incrementing the version
   (major|minor|patch), create a new commit with the version change,
   create a tag for the version, and prepare for the next development
   iteration.
3. Inspect the commits/tag and push to master. This will trigger the
   github release workflow which is triggered for new tags which will
   then publish a new release on github.

Example usage:
```console
$ ./scripts/release.sh major --dry-run
[dry-run] - No changes will be made

Step 1: Reading current version...
Current version: 0.9.0-dev
New release version: 1.0.0

Step 2: Updating version in ggml/CMakeLists.txt...
  [dry-run] Would update GGML_VERSION_MAJOR to 1
  [dry-run] Would update GGML_VERSION_MINOR to 0
  [dry-run] Would update GGML_VERSION_PATCH to 0
  [dry-run] Would remove -dev suffix

Step 3: Committing version bump...
  [dry-run] Would commit: 'ggml : bump version to 1.0.0'

Step 4: Creating git tag...
  [dry-run] Would create tag: v1.0.0 with message 'Release version 1.0.0'

Step 5: Preparing for next development cycle...
  [dry-run] Would update GGML_VERSION_MINOR to 1
  [dry-run] Would add -dev suffix back

Step 6: Committing development version...
  [dry-run] Would commit: 'ggml : prepare for development of 1.1.0-dev'

[dry-run] Summary (no changes were made):
  • Would have released version: 1.0.0
  • Would have created tag: v1.0.0
  • Would have set next development version: 1.1.0-dev
```

ggml-amx : fix ggml_amx_init() on generic Linux (#16049)

cmake : fix static linking for OpenMP on Unix-like systems (#16031)
When compiling with GGML_STATIC=ON, the build process would produce a
binary that was still dynamically linked to OpenMP. This defeats the
purpose of a static build:

    $ cmake -B build \
            -DBUILD_SHARED_LIBS=OFF \
            -DLLAMA_CURL=OFF \
            -DGGML_CCACHE=OFF \
            -DGGML_NATIVE=OFF \
            -DGGML_STATIC=ON

    $ ldd llama-server
            linux-vdso.so.1 (0x0000e1a434e3b000)
            libgomp.so.1 => /lib/aarch64-linux-gnu/libgomp.so.1 (0x0000e1a4345a0000)
            libstdc++.so.6 => /lib/aarch64-linux-gnu/libstdc++.so.6 (0x0000e1a434300000)
            libm.so.6 => /lib/aarch64-linux-gnu/libm.so.6 (0x0000e1a434240000)
            libgcc_s.so.1 => /lib/aarch64-linux-gnu/libgcc_s.so.1 (0x0000e1a434200000)
            libc.so.6 => /lib/aarch64-linux-gnu/libc.so.6 (0x0000e1a434030000)
            /lib/ld-linux-aarch64.so.1 (0x0000e1a434df0000)

This commit resolves the issue by modifying `CMAKE_FIND_LIBRARY_SUFFIXES`
to prioritize `.a` files, forcing CMake to link the static version of
the library.

CANN: Optimize ggml_cann_set_device (#15935)
* CANN: Fix ggml_cann_set_device to avoid redundant device switches

- Added a check to skip aclrtSetDevice if the current device is already set.
- Prevents unnecessary context switches while keeping thread/device consistency.

* CANN: add device default id

ggml : fix padding in timestep embedding kernels (#15932)
* ggml : remove adding extra dim timestep embedding

This commit updates the ggml_timestep_embedding function to no longer
add an extra dimension when the specified dimension is odd.

The motivation for this change is that this introduces an unnecessary
dimension when the dimension is odd, which caused an issue in the
kernels which were not expecting this extra dimension and it resulted in
uninitialized memory for the second to last dimension.

* ggml-cuda : fix padding in timestep embedding kernel

This commit removes the zeroing out of the last dimension now that we
are not adding the extra padding dimension.

* ggml-metal : fix padding in timestep embedding kernel

This commit fixes the zero padding for odd dimensions in
the timestep embedding kernel

* ggml-opencl : fix padding in timestep embedding kernel

This commit fixes the zero padding for odd dimensions in
the timestep embedding kernel.

* ggml-sycl : fix padding in timestep embedding kernel

This commit fixes the zero padding for odd dimensions in
the timestep embedding kernel.

* ggml-vulkan : fix padding in timestep embedding kernel

This commit fixes the zero padding for odd dimensions in
the timestep embedding kernel.

* ggml-cpu : fix padding in timestep embedding function

This commit removes the zeroing out of the last dimension now that we
are not adding the extra padding dimension.

CUDA: fix im2col_3d to respect non-contiguous inputs (views) (#15956)
* fix im2col_3d to respect non-contiguous inputs (views)

The CUDA 3D im2col kernel computed source addresses assuming compact layout (products of dims), ignoring nb[] strides. 

This patch switches im2col_3d source indexing to use true strides derived from src1->nb[] (in elements), mirroring the approach used in the 2D CUDA im2col path. Destination indexing is unchanged.

* use ggml_element_size() for src strides
