gguf-py: validate n_dims and guard against uint64 overflow in reader (#25401) 
The Python GGUF reader lacked two guards the C++ loader has:
- n_dims read as uint32 with no GGML_MAX_DIMS bound -> crafted file with
  huge n_dims triggers oversized memmap read / OOM.
- np.prod(dims) on uint64 wraps silently -> a crafted dims triple can
  overflow to a tiny element count, passing an undersized read through.

Add a GGML_MAX_DIMS check and compute the element count with Python ints.

Fixes #25378
