[BOLT][DRAFT] Enable binary stripping

[paschalis-mpeis]

The patch toggles on -remove-symtab, checks compatibility with other flags, and omits sections that are removed by tools like llvm-strip.

This is a draft patch mostly to assess where we stand in terms of a bolt implementation that does binary stripping. It looks like it's close to what strip tools remove from binaries or am I missing anything substantial here?

This draft PR was meant to be a quick exercise to see how one could support stripping in BOLT.
It turns out the next day this patch was published that can fix stripping for gnu strip:
https://sourceware.org/git/?p=binutils-gdb.git;a=commitdiff;h=bbc969306f8d5fb6c7b636e25f6f8e278946ef23

TMU, llvm-strip was fixed and now I assume the same for gnu strip, so probably issues #56738 and duplicate #89336 are now resolved.

Given the stripping tools can now properly handle this, I don't see a need for BOLT to duplicate such functionality.
If that somehow changes, we can re-visit this PR.
