Add architecture-specific code paths for aarch64 in the PyPerf eBPF Python profiler. This removes the 'Unsupported platform' error on aarch64 and enables PyPerf to profile Python processes on ARM64/Graviton. Changes: - PyPerfBPFProgram.cc: aarch64 TLS access via TPIDR_EL0, user-mode detection via pstate, register mapping (pc/x29), no red zone - PyPerfNativeStackTrace.cc: libunwind aarch64 register handling - PyPerf.cc/PyPerfProfiler: --pthread-struct-size argument - CMakeLists.txt: conditional libunwind-aarch64 linking Tested on AWS Graviton (m9g.metal-48xl), kernel 6.17, Ubuntu 24.04, glibc 2.39, Python 3.12.
