Validate hardcoded offsets to PROFILE_PLATFORM_SPECIFIC_DATA struct

[tomeksowi]

These offsets are now in asmconstants.h validated against the C struct with static asserts.

This refactoring is a follow-up to discussion under PR #91313.

Note: I didn't define offset constants for i386 because its asm profile stubs are based on a sequence of pushes rather than field offsets so they wouldn't use them.

Part of #84834

I think I need some time to refactor some function to fix some errors for LoongArch. Maybe tomorrow is ok.

Or you just merge this PR liking your headline said this is just a refacting struct _PROFILE_PLATFORM_SPECIFIC_DATA.

I will fix some errors within the profiler.cpp and the struct fields later by a new PR.
Is this OK？

It's OK with me to merge this as-is and fix LoongArch specifics later.

BTW, from what I noticed ELT profiler on LoongArch64 isn't called at all, genProfiling(Enter|Leave)Callback are a no-op. Given the arch similarity, I think you can base your implementation off of mine in PR #91313.
