gh-139353: Add Objects/unicode_writer.c file (#139911) 
Move the public PyUnicodeWriter API and the private _PyUnicodeWriter
API to a new Objects/unicode_writer.c file.

Rename a few helper functions to share them between unicodeobject.c
and unicode_writer.c, such as resize_compact() or unicode_result().

return/break/continue in finally (see PEP-765) -- they are only
emitted during compilation.

GH-139951: Fix major GC performance regression (GH-140262) 
* Count number of actually tracked objects, instead of trackable objects. This ensures that untracking tuples has the desired effect of reducing GC overhead

* Do not track most untrackable tuples during creation. This prevents large numbers of small tuples causing execessive GCs.

gh-140067: Fix memory leak in sub-interpreter creation (#140111) (#140261) 
Fix memory leak in sub-interpreter creation caused by overwriting of the previously used `_malloced` field. Now the pointer is stored in the first word of the memory block to avoid it being overwritten accidentally.

gh-139877: Use PyBytesWriter in pycore_blocks_output_buffer.h (#139976) 
Previously, the _BlocksOutputBuffer code creates a list of bytes objects to handle the output data from compression libraries. This ends up being slow due to the output buffer code needing to copy each bytes element of the list into the final bytes object buffer at the end of compression.

The new PyBytesWriter API introduced in PEP 782 is an ergonomic and fast method of writing data into a buffer that will later turn into a bytes object. Benchmarks show that using the PyBytesWriter API is 10-30% faster for decompression across a variety of settings. The performance gains are greatest when the decompressor is very performant, such as for Zstandard (and likely zlib-ng). Otherwise the decompressor can bottleneck decompression and the gains are more modest, but still sizable (e.g. 10% faster for zlib)!
