…for extension modules (GH-26025) (#26028)

The address tuple for CAN_RAW no longer returns the address family
after the introduction of CAN ISO-TP support in a30f6d4. However,
updating test_socket.CANTest.testSendFrame was missed as part of the
change, so the test incorrectly attempts to index past the last tuple
item to retrieve the address family.

This removes the now-redundant check for equality against socket.AF_CAN,
as the tuple will not contain the address family.

* bpo-41100: Support macOS 11 and Apple Silicon on Python 3.8

This is a partial backport of bpo-41100 changes `e8b1c038b14b5fc8120aab62c9bf5fb840274cb6` and `96d906b144e6e6aa96c5ffebecbcc5d38034bbda` for Python 3.8. We introduce the ability to build Python from source for `arm64` on macOS, but we do not make a promise of support. This allows us to omit support for Universal2 binaries as well as weak-linking of symbols from the macOS SDK based on the deployment target, which are larger changes much more difficult to merge.

This also includes a backport of subsequent bpo-42688 change `7e729978fa08a360cbf936dc215ba7dd25a06a08` to fix build errors with external `libffi`.

* bpo-41116: Ensure system supplied libraries are found on macOS 11 (GH-23301) (GH-23455)

On macOS system provided libraries are in a shared library cache
and not at their usual location. This PR teaches distutils to search
in the SDK, even if there was no "-sysroot" argument in
the compiler flags.
(cherry picked from commit 404a719)

* bpo-42504: fix for MACOSX_DEPLOYMENT_TARGET=11 (GH-23556)

macOS releases numbering has changed as of macOS 11 Big Sur.  Previously, major releases were of the form 10.x, 10.x+1, 10.x+2, etc; as of Big Sur, they are now x, x+1, etc, so, for example, 10.15, 10.15.1, ..., 10.15.7, 11, 11.0.1, 11.1, ..., 12, 12.1, etc. Allow Python to build with single-digit deployment target values. Patch provided by FX Coudert.

…eption (GH-23872)

Links for 'raise Exception from x' target to 'The raise statement' (7.8) section instead of 'The import statement' (7.11) section.

There are more modified links than in the bug report because I searched some other ones which can get the same improvement..
(cherry picked from commit 2fd928c)

This PR is a cherry pick to python 3.8 from #23872. The fix was the removal of the change in the other file because the fixed section was introduced in 3.9. So the file does not need to be fixed in 3.8.
