Notes for future upgrade to Rust 1.84

[seritools]

Things to check:

• Windows: Allow File::create to work on hidden files rust-lang/rust#116438

[seritools]

• From Chris Denton on discord:

Oh yeah, I made a few small changes t'other day, Might be in nightly by now:

GetSystemTimePreciseAsFileTime is now imported directly
Use ProcessPrng (because BCryptGenRandom crashes firefox)
Always use WaitOnAddress

These do not affect the win7 target tho.

Will need to extend the added #[cfg(not(target_vendor = "win7"))] checks

[seritools]

• integrate fix for try_lock() always reports "WouldBlock" #21 into the mutex implementation PR when rebasing. will also need to move the version.rs creation to before that.

[seritools]

• check Windows: Implement condvar, mutex and rwlock using futex rust-lang/rust#121956

[seritools]

• check if Tracking Issue for lazy_cell rust-lang/rust#109736 will cause issues

[seritools]

• Link MSVC default lib in core rust-lang/rust#122268 check linking
• https://doc.rust-lang.org/stable/std/path/fn.absolute.html check impl of this

[seritools]

• pal module for platform abstractions
• TLS refactor: std: refactor the TLS implementation rust-lang/rust#126523 ---- i think this is not needed anymore since 32bit windows has now target_thread_local enabled again, will need to check

[seritools]

• Implement fallback for new LockFileEx usage (seems like LockFile would just work instead)
