* gh-98154: Clarify Usage of "Reference Count" In the Docs (gh-107552)
PEP 683 (immortal objects) revealed some ways in which the Python documentation has been unnecessarily coupled to the implementation details of reference counts. In the end users should focus on reference ownership, including taking references and releasing them, rather than on how many reference counts an object has.
This change updates the documentation to reflect that perspective. It also updates the docs relative to immortal objects in a handful of places.

gh-107471: Fix Refleaks in test_import (gh-107569)
gh-107184 introduced a refleak in test_import.SubinterpImportTests (specifically test_singlephase_check_with_setting_and_override and test_single_init_extension_compat). We fix it here by making sure _testsinglephase is removed from sys.modules whenever we clear the runtime's internal state for the module.
The underlying problem is strictly contained in the internal function _PyImport_ClearExtension() (AKA _testinternalcapi.clear_extension()), which is only used in tests.
(This also fixes an intermittent segfault introduced in the same place, in test_disallowed_reimport.)

gh-106092: Fix use-after-free crash in frame_dealloc (GH-106875)
It was possible for the trashcan to delay the deallocation of a
PyFrameObject until after its corresponding _PyInterpreterFrame has
already been freed. So frame_dealloc needs to avoid dereferencing the
f_frame pointer unless it first checks that the pointer still points
to the interpreter frame within the frame object.
