Manual backport notes

A pure cherry-pick conflicted because 3.15 does not have the marshal error handling changes of gh-156942 and gh-155907, nor gh-148653.

• Python/marshal.c: keeps the WFERR_* error codes of this branch; the new allocation failures use WFERR_NOMEMORY.
• PyMarshal_WriteLongToFile() and PyMarshal_WriteObjectToFile() still do not report a failure to write to the file, as before on this branch.
• PyMarshal_WriteObjectToFile() now goes through the same code as marshal.dumps(), so when the object cannot be marshalled it writes nothing and sets ValueError. Before, it wrote partial data and usually returned without an error.
• Recursive tuples are not detected on this branch (Crash: marshal.loads SIGSEGV on self-referencing TYPE_TUPLE with FLAG_REF #148653), so test_shared_recursion uses a recursive slice.
• Lib/test/test_capi/test_marshal.py does not exist here: its new cases are in CAPI_TestCase of Lib/test/test_marshal.py, and the _testcapi helper returns the error instead of asserting there is none.
• Doc/c-api/marshal.rst: the notes about unreported write errors no longer say "In Python 3.15 and earlier"; the versionchanged entry describes the change.
• Programs/test_frozenmain.h is regenerated.

• Issue: Bytecode compilation output depends on order of files compiled #129724
