repl: Add inlay repl output display, skip empty lines on execution, and gutter execution display (#44523)
Adds various useful things to the repl inspired by ipynb and the julia
vscode extension which can be best seen with this video:

To summarize:

## Inline outputs
Added small, single-line outputs displayed inline at the end of the code
line instead of in a separate block. This provides a cleaner, more
compact view for simple results like numbers or short strings. This
occurs for execution views who only output a single mimetype/plain OR
output nothing, otherwise the default behavior of creating a block will
occur.

It looks like this:

/>
or with a Output

/>
This was inspired by julia vscode extension, but now it can be used with
any replanguage! Hooray!

It saves lots of space compared to the ugly and distracting:

/>


## Gutters and execution numbers
Added gutters + execution number to display exactly what was executed.
The gutter highlighting is useful for when selecting multiple cells
manually to run, but you dont remember which ones

Ran at different times:

/>
Ran together:

/>

The execution number is useful in the same way that a normal jupyter
notebook execution number is useful.

If a gutter-region does not have a block assigned to it, when you edit
the text in the gutter region, the gutter will disappear, which is
useful for telling when you have modified your code, but does not delete
useful experiment results in blocks:

/>
 
## Skip empty line
This is a minor fix which is intended to make lab workflow less tedious.
Currently when you execute on an empty line (which might be there for
formatting purposes) nothing will occur. This PR adds the ability to,
when executing from an empty line, skip ahead the range of inclusion
until you reach actual code, and then execute.

Before:
```
code //run execute
//empty space, so you have to move your cursor down or use arrow key
code //run execute
code //run execute
```
After:
```
code //run execute
//empty space, you can now run execute on it and it will include the next line of code
//empty space
code //automatically executed
code //run execute
```

Currently the only piece of tested code is related to this, i still have
to write tests for the gutter annotation api i added and all of the
gutter + inline related code. Also still have to add more config for
this stuff.

@rgbkrk would appreciate a review :D

Closes #22678

Release Notes:

- repl: Added an inline display of execution results (as opposed to the
large execution view) for simple REPL cells
- repl: Improved how execution of empty lines are handled
