0aa22dcd - [OpenMP][AArch64] Fix branch protection in microtasks (#102317)

[OpenMP][AArch64] Fix branch protection in microtasks (#102317) Start __kmp_invoke_microtask with PACBTI in order to identify the function as a valid branch target. Before returning, SP is authenticated. Also add the BTI and PAC markers to z_Linux_asm.S. With this patch, libomp.so can now be generated with DT_AARCH64_BTI_PLT when built with -mbranch-protection=standard. The implementation is based on the code available in compiler-rt.
