[parser] Fix panic when parsing IPython escape command expressions (#21480)
## Summary

Fixes a panic when parsing IPython escape commands with `Help` kind
(`?`) in expression contexts. The parser now reports an error instead of
panicking.

Fixes #21465.

## Problem

The parser panicked with `unreachable!()` in
`parse_ipython_escape_command_expression` when encountering escape
commands with `Help` kind (`?`) in expression contexts, where only
`Magic` (`%`) and `Shell` (`!`) are allowed.

## Approach

Replaced the `unreachable!()` panic with error handling that adds a
`ParseErrorType::OtherError` and continues parsing, returning a valid
AST node with the error attached.

## Test Plan

Added `test_ipython_escape_command_in_with_statement` and
`test_ipython_help_escape_command_as_expression` to verify the fix.
