This implements MWAITX and WAITPKG extensions (umonitor, mwait) for CPUs that support them.
Reduces wait times and bypasses the timing stuff from the OS that is slow (windows notably). generally it should answer within 0.2 to 0.5 microsecs (since most requests wait for that long).
Also does a general rework of static ctors and stuff

Closes#3344
Adds slow and turbo modes with configurable speeds that can then be
toggled by the user. Behavior is:
- Standard/slow limit, toggle turbo = turbo
- Turbo limit, toggle turbo = standard
- Standard/turbo limit, toggle slow = slow
- Slow limit, toggle slow = standard
Enabling the turbo/slow mode enables the frame limiter unconditionally.
This has some conflicts with VSync. For example when I set my refresh
rate to 60hz and enable vsync, turbo mode does nothing. Not sure how to
go about fixing this, @MaranBr probably knows better the proper
solution.

for core stuff:
just remove unique ptrs that dont need any pointer stability at all (afterall its an allocation within an allocation so yeah)
for fibers:
Main reasoning behind this is because virtualBuffer<> is stupidly fucking expensive and it also clutters my fstat view
ALSO mmap is a syscall, syscalls are bad for performance or whatever
ALSO std::vector<> is better suited for handling this kind of "fixed size thing where its like big but not THAT big" (512 KiB isn't going to kill your memory usage for each fiber...)
for core.cpp stuff
- inlines stuff into std::optional<> as opposed to std::unique_ptr<> (because yknow, we are making the Impl from an unique_ptr, allocating within an allocation is unnecessary)
- reorganizes the structures a bit so padding doesnt screw us up (it's not perfect but eh saves a measly 44 bytes)
- removes unused/dead code
- uses std::vector<> instead of std::deque<>
no perf impact expected, maybe some initialisation boost but very minimal impact nonethless
lto gets rid of most calls anyways - the heavy issue is with shared_ptr and the cache coherency from the atomics... but i clumped them together because well, they kinda do not suffer from cache coherency - hopefully not a mistake
this balloons the size of Impl to about 1.67 MB - which is fine because we throw it in the stack anyways
REST OF INTERFACES: most of them ballooned in size as well, but overhead is ok since its an allocation within an alloc, no stack is used (when it comes to storing these i mean)

- Fast GPU now defaults to 256, removed 128 since it's useless.
- Completely reorganized graphics and CPU settings on both platforms.
Also got rid of Eden's Veil
- Merged some "use ..." settings that weren't really necessary.
- Changed ExtendedDynamicState to be a combo box

Previously, we were mixing the raw CPU frequency and CNTFRQ.
The raw CPU frequency (1020 MHz) should've never been used as CNTPCT (whose frequency is CNTFRQ) is the only counter available.
The precision of sleep_for and wait_for is limited to 1-1.5ms on Windows.
Using SleepForOneTick() allows us to sleep for exactly one interval of the current timer resolution.
This allows us to take advantage of systems that have a timer resolution of 0.5ms to reduce CPU overhead in the event loop.
