* improve signal emulation
* make the sce function use the new posix ones
* ifdefing away the issues
* fix me being very tired yesterday night
* let macOS handle SIGRT signals with the native sigaction call instead of an early error return
* windows still has no clue what the fuck is going on
* the loathsome clang-formatter
* fix oact
* return the guest handler, not the host one
* Clear any existing signal mask for game threads.
* don't rely on implementation specific things
* Fix Windows support and sceKernelRaiseException bug
* Review suggestions
@kalaposfos13 suggested I push these.

* Remove SceKernelInternalMemory mapping
Contrary to my initial beliefs, this is very much a hack.
* Unreachable for unpatched code
This will always infinitely loop, making logs extremely large.
* Update linker.cpp
* Patch stack checks done using fs:[0x28]
Additionally adds support for multiple patches per instruction, since this makes two separate patches we need to conditionally perform for mov instructions.
* Missing include
* Disable patches for Apple
Mac can use their native FS segment directly, so these patches aren't needed
* Oops
* cpu_patches: Remove CPU patches for macOS and bump minimum OS version to 15.4
* cpu_patches: Remove BMI1 patches
These are now only good for very old Intel CPUs that:
* Still do not currently function due to other CPU instruction issues.
* Will probably be too slow to run shadPS4 well.
* Use a singleton for instruction decoding
* Use singleton class
* Patch `EXTRQ`
* Fixup signal context functions
* Update CMakeLists.txt

* cpu_patches: Patch just-in-time using illegal instruction handler.
* core: Add common signal dispatch system and use for on-demand TCB patches.
* page_manager: Re-add userfaultfd implementation.
