Migration to GitHub Actions

[esc]

This issue tracks the progress migrating the llvmlite project testing and artifact production from an Anaconda internal system to GitHub actions.

We need to support creating the llvmdev and llvmlite packages. llvmdev is a utility package for LLVM that is included (statically linked) in the llvmlite packages. Packages come in two flavours: conda packages and wheels. We need to produce all llvmdev packages for currently supported architectures: win-64, osx-64, osx-arm64, linux-64 and linux-aarch64. We need to produce all llvmlite packages for the currently supported architectures and also for the currently supported Python versions : 3.10, 3.11, 3.12 and 3.13 for each architecture.

llvmdev for wheel workflow fails for 3 platforms currently- osx-64, linux-64 and linux-aarch64.

• osx-64-
  https://github.com/numba/llvmlite/actions/runs/13908533082.
  This is a known issue and has been fixed here - fix llvmdev osx64 conda builder #1167
  The fix is impending llvmlite osx-64 workflow testing to validate dlls.

• linux64-

  https://github.com/numba/llvmlite/actions/runs/1390851399
  likely runtime library mismatch, in-progress

llvmlite osx-64 wheel workflow - #1187.

This needed using older SDK available on runner - MACOSX_DEPLOYMENT_TARGET=10.13.
switching to xcode 14.1.0 provides toolchain and sdk.

llvmlite conda builder osx64 based off llvmdev osx64 fix - #1186

[swap357]

updated PR for llvmlite conda builder osx64 here: #1190
closed the older one #1186, as it needed rebasing (with conflicts), the history remains clean this way.

Please consider adding win-arm64 wheels support

Please consider adding win-arm64 wheels support

can you open a new issue for this request please, it's beyond the scope of this ticket.

This is a screenshot of all the implemented current workflows. By the filename you can see that 5 architectures (linux-64, linux-arm64, win-64, osx-64 and osx-arm64) for two package flavours (wheel and conda) have been implemented. For llvmdev there is a single workflow that takes care of all architectures.

As a result we can check all the boxes now since this task is complete.
