gha/restructure llvmdev ci

[swap357]

This PR introduces several key fixes to the llvmdev GHA build process.

• adds user input options - 'all' for platforms and recipe. allows running all llvmdev workflows using one click/workflow dispatch. This also helps input only one workflow id on downstream llvmlite workflows.
• builds llvmdev_for_wheel inside manylinux containers for linux-64 and linux-arm64 to ensure wheel compatibility.
• pins the osx-64 compiler to version 14 to avoid conda selecting 17.x compilers.
• fixes linux-arm64 builds by pinning py-lief to a version older than 0.16.
• standardizes the use of linux-arm64 as the platform identifier.
