Adds a PrivacyInfo.xcprivacy file when packaging `_hashlib` and `_ssl` modules
for iOS (based on the original OpenSSL sources); and adds handling to the build
script to allow any app to add `xcprivacy` handling for a binary module.
Adds tooling to generate and test an iOS XCframework, in a way that will also facilitate
adding other XCframework targets for other Apple platforms (tvOS, watchOS, visionOS and
even macOS, potentially).

Modifies the iOS testbed project to add a test plan. This simplifies the iOS
test runner, as we can now use the built-in log streaming to see test results.
It also allows for some other affordances, like providing a default LLDB config,
and using a standardized mechanism for specifying test arguments.
* Doc/c-api/memory.rst: extend --without-pymalloc doc with ASan information
This commit extends the documentation for disabling pymalloc with the `--without-pymalloc` flag regarding why it is worth to use it when enabling AddressSanitizer for Python build (which is done, e.g., in CPython's CI builds).
I have tested the CPython latest main build with both ASan and pymalloc enabled and it seems to work just fine. I did run the `python -m test` suite which didn't uncover any ASan crashes (though, it detected some memory leaks, which I believe are irrelevant here).
I have discussed ASan and this flag with @encukou on the CPython Core sprint on EuroPython 2025. We initially thought that the `--without-pymalloc` flag is needed for ASan builds due to the fact pymalloc must hit the begining of page when determining if the memory to be freed comes from pymalloc or was allocated by the system malloc. In other words, we thought, that ASan would crash CPython during free of big objects (allocated by system malloc). It may be that this was the case in the past, but it is not the case anymore as the `address_in_range` function used by pymalloc is annotated to be skipped from the ASan instrumentation.
This code can be seen here:
https://github.com/python/cpython/blob/acefb978dcb5dd554e3c49a3015ee5c2ad6bfda1/Objects/obmalloc.c#L2096-L2110
While the annotation macro is defined here:
https://github.com/python/cpython/blob/acefb978dcb5dd554e3c49a3015ee5c2ad6bfda1/Include/pyport.h#L582-L598
And the corresponding attribute is documented in:
* for gcc: https://gcc.gnu.org/onlinedocs/gcc/Common-Function-Attributes.html#index-no_005fsanitize_005faddress-function-attribute
* for clang: https://clang.llvm.org/docs/AttributeReference.html#no-sanitize-address-no-address-safety-analysis
* Update Doc/c-api/memory.rst
* Improve --with-address-sanitizer and pymalloc docs

The iOS testbed now treats the app_packages folder as a site folder. This ensures it is
on the path, but also ensures any .pth files are processed on app startup.
Remove `experimental` qualification for free-threading in the document text. Note that images included in the document will be updated later in the release cycle.
Modifies the environment handling and execution arguments of the Android management
script to support the compilation of third-party binaries, and the use of the testbed to
invoke third-party test code.
