[3.13] gh-136541: Fix several problems of perf trampolines in x86_64 and aarch64 (GH-136500) (#136545)

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
(cherry picked from commit 236f733d8ffb3d587e1167fa0a0248c24512e7fd)
