In this refactor we:
* move some code around
* make a couple of typedefs opaque
* decouple errors from session state
* improve tracebacks for propagated exceptions
This change helps simplify several upcoming changes.

gh-91048: Refactor and optimize remote debugging module (#134652)
Completely refactor Modules/_remote_debugging_module.c with improved
code organization, replacing scattered reference counting and error
handling with centralized goto error paths. This cleanup improves
maintainability and reduces code duplication throughout the module while
preserving the same external API.
Implement memory page caching optimization in Python/remote_debug.h to
avoid repeated reads of the same memory regions during debugging
operations. The cache stores previously read memory pages and reuses
them for subsequent reads, significantly reducing system calls and
improving performance.
Add code object caching mechanism with a new code_object_generation
field in the interpreter state that tracks when code object caches need
invalidation. This allows efficient reuse of parsed code object metadata
and eliminates redundant processing of the same code objects across
debugging sessions.
Optimize memory operations by replacing multiple individual structure
copies with single bulk reads for the same data structures. This reduces
the number of memory operations and system calls required to gather
debugging information from the target process.
Update Makefile.pre.in to include Python/remote_debug.h in the headers
list, ensuring that changes to the remote debugging header force proper
recompilation of dependent modules and maintain build consistency across
the codebase.
Also, make the module compatible with the free threading build as an extra :)

This is mostly a refactor to clean things up a bit, most notably the "XI namespace" code.
Making the session opaque requires adding the following internal-only functions:
* _PyXI_NewSession()
* _PyXI_FreeSession()
* _PyXI_GetMainNamespace()

It now supports a "full" fallback to _PyFunction_GetXIData() and then `_PyPickle_GetXIData()`.
There's also room for other fallback modes if that later makes sense.

error handler (GH-129648) (GH-133942)
If the error handler is used, a new bytes object is created to set as
the object attribute of UnicodeDecodeError, and that bytes object then
replaces the original data. A pointer to the decoded data will became invalid
after destroying that temporary bytes object. So we need other way to return
the first invalid escape from _PyUnicode_DecodeUnicodeEscapeInternal().
_PyBytes_DecodeEscape() does not have such issue, because it does not
use the error handlers registry, but it should be changed for compatibility
with _PyUnicode_DecodeUnicodeEscapeInternal().

Also add the python3.14.abi file as generated by the new job and remove
the 'main branch only' entry from .gitignore.
The only difference from the 3.13 job is the addition of `with.python-version: 3.x`
to the `setup-python` configuration to pacify a warning.
