gh-149800: Split perf trampoline assembly into per-architecture files

• Issue: Refactor perf trampoline proposal: split the assembly per architecture, auto-generate DWARF unwind data #149800

I believe this is a candidate for skip-news since it's refactoring.

I've tested the combinations on x86_64 and aarch64. Final binary has the proper hardware protections when used and gnu notes, perf tests pass, -Xperf and -Xperf_jit works fine through my testing and also for completeness I tested out of tree builds and they are fine as well.

For the build part I haven't tested the macOS, I don't have access to a machine, this needs to be verified. I followed there a similar convention as the jit_shim object.

Noting that the RISC-V support is broken, hence the lack of configure target, I just moved the assembly to its own file, I plan to provide a PR to fix it in the future, but hopefully after the implementation of automatic generation of dwarf info.
