Musl testing

[bretambrose]

• Add an additional native artifact directory component for C runtime
• Add Musl detection in build (CMakeLists.txt) and at runtime
• Add Musl-based CI; remove old cross-compiled arm CI in favor of the Musl-based arm jobs. Keep both as cross-compiled are used with Glibc.
• Add environment/system property override for architecture selection to support ambiguous (arm6 vs arm7) cases
• Tweak some tests to work in a Musl-based environment

I made the following changes

• Removes Alpine profile and different Surefire version, that is not needed.
• Fix musl build script to correctly mount the source and use that instead of pulling from Github.
• Keep previous cross compile jobs as they use glibc.
• Add CI and CD scripts for armv7 and armv8.
• Use Qemu from ECR. Docker has a pull limit for users, and I encountered issues during testing due to this limit. I will update the builder to keep this image up-to-date
