Support aarch64 wheel Builds

Closes #178

Firstly, here's a working CI build: https://github.com/iofq/ffpyplayer/actions/runs/15224996925/job/42826871473

The Test step failed once on OSX, but succeeded the second time and appears to just be a race condition/performance issue: https://github.com/iofq/ffpyplayer/actions/runs/15224996925/job/42826871473#step:9:160

Summary of Changes

• x265:
  x265's CMake files cease to work on CMake v4+ due to policy deprecations. The issue was fixed in x265 upstream in https://bitbucket.org/multicoreware/x265_git/commits/b354c009a60bcd6d7fc04014e200a1ee9c45c167. CMake 4.0 was introduced to the manylinux2014 Docker images we're using in pypa/manylinux@dc69f53#diff-12364f0a1989d08e72d764980ee91edcffd0c6cc162b143b21daae8e31f6d76e. I elected to pull the two patches needed to fix this for x265 (present in x265 master branch but not backported) and apply them.

• brotli:
  On OSX, brotli suffered the same CMake fate, but I chose to use the CMake flag -DCMAKE_POLICY_VERSION_MINIMUM=3.5 as the CMake-recommended workaround, rather than trying to patch the CMakeLists.txt file ourselves, since there is not an upstream patch available.

• libtheora:
  On OSX, libtheora was bumped to version 1.2.0, which was a long-awaited release (1.1.1 was released in 2009) and contains compilation fixes for modern systems. Additionally, changed the THEORA_ARCH variable to use the correct host triplet for configure.

• CI Pipeline:
  Updated to use the new GitHub Actions ARM runners (far faster than QEMU) for ARM wheel compilation and testing. Also, bumped cibuildwheel to the latest version.

Thank you!! I'll make a release at some point soon, if you're happy with the generated wheels.

[iofq]

a release would be great, we're aiming to use these for some upstream packaging in NixOS/nixpkgs#408590

Released the latest version. Thanks for the PR!!
