gh-136541: Fix several problems of perf trampolines in x86_64 and aarch64 (#136500)

This commit fixes the following problems:

* The x86_64 trampolines are not preserving frame pointers
* The hardcoded offsets to the code segment from the FDE only worked properly for x64_64
* The CIE data was not following conventions of aarch64
* The eh_frame for aarch64 was not fully correct
