kernel: Rewrite pthread emulation (#1440)

Browse source 
* libkernel: Cleanup some function places

* kernel: Refactor thread functions

* kernel: It builds

* kernel: Fix a bunch of bugs, kernel thread heap

* kernel: File cleanup pt1

* File cleanup pt2

* File cleanup pt3

* File cleanup pt4

* kernel: Add missing funcs

* kernel: Add basic exceptions for linux

* gnmdriver: Add workload functions

* kernel: Fix new pthreads code on macOS. (#1441)

* kernel: Downgrade edeadlk to log

* gnmdriver: Add sceGnmSubmitCommandBuffersForWorkload

* exception: Add context register population for macOS. (#1444)

* kernel: Pthread rewrite touchups for Windows

* kernel: Multiplatform thread implementation

* mutex: Remove spamming log

* pthread_spec: Make assert into a log

* pthread_spec: Zero initialize array

* Attempt to fix non-Windows builds

* hotfix: change incorrect NID for scePthreadAttrSetaffinity

* scePthreadAttrSetaffinity implementation

* Attempt to fix Linux

* windows: Address a bunch of address space problems

* address_space: Fix unmap of region surrounded by placeholders

* libs: Reduce logging

* pthread: Implement condvar with waitable atomics and sleepqueue

* sleepq: Separate and make faster

* time: Remove delay execution

* Causes high cpu usage in Tohou Luna Nights

* kernel: Cleanup files again

* pthread: Add missing include

* semaphore: Use binary_semaphore instead of condvar

* Seems more reliable

* libraries/sysmodule: log module on `sceSysmoduleIsLoaded`

* libraries/kernel: implement `scePthreadSetPrio`
