aarch64 build fixes for 2.19.1 (WIP)

[dslarm]

This PR will get us going again on linux-aarch64

• remove previous python package id limits
• fix build issue in xla

Work in progress:

• Locally this reaches the end of the compilation phase (no C++ compile errors :0), but there's a wheels problem:

• a) it looks to me like it's trying to make x86_64 ones when doing aarch64 - although that does not error (surely it should.) - smells like it's from the bazel part of the build:

[17,433 / 17,437] Writing: bazel-out/aarch64-opt/bin/tensorflow/tools/lib_package/libtensorflow.tar.gz; 35s local ... (3 actions running)

and

• b) it particularly doesn't like python 3.12:

Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe/meta.yaml) and found it was in an excellent condition.

I do have some suggestions for making it better though...

For recipe/meta.yaml:

• ℹ️ The recipe is not parsable by parser conda-souschef (grayskull). This parser is not currently used by conda-forge, but may be in the future. We are collecting information to see which recipes are compatible with grayskull.
• ℹ️ The recipe is not parsable by parser conda-recipe-manager. The recipe can only be automatically migrated to the new v1 format if it is parseable by conda-recipe-manager.

also need to check this line from the build output:

WARNING (libtensorflow_cc): run-exports library package conda-forge/linux-aarch64::libstdcxx-ng==15.2.0=hf1166c9_7 in requirements/run but it is not used (i.e. it is overdepending or perhaps statically linked? If that is what you want then add it to `build/ignore_run_exports`)

• aarch64 builds are restricted to using gcc11 at the moment - so wasn't expecting to see 15.x.x

also need to check this line from the build output:

This is fine. We always use the newest C++ standard library implementation, even if you compile with older compiler versions. That works because the standard libraries (libcxx and libstdcxx) are highly backwards compatible

Same error as you noted in the OP already

+ PY_VER=3.12
+ $PREFIX/bin/python -m pip install --no-deps $SRC_DIR/tensorflow_pkg/tensorflow-2.19.1-cp312-cp312-linux_x86_64.whl
ERROR: tensorflow-2.19.1-cp312-cp312-linux_x86_64.whl is not a supported wheel on this platform.

This will probably require patching the bazel files
