Memory rework pt 2 (#801)

* Memory: Rework FCRAM management entirely

Disables a lot of functionality... but I didn't want to commit too much to this commit
Also reworks virtual memory management somewhat (but needs more work)

* Accurately handle MemoryState for virtual memory

Previously all non-free blocks were marked as Reserved

* Memory: Consolidate state and permission changes

Can now use a single function to change either state, permissions, or both
Also merge vmem blocks that have the same state and permissions

* Memory: Fix double reset for FCRAM manager

Fix minor bug with permission tracking

* Memory: Implement Protect operation in ControlMemory

* Memory: Implement Unmap in ControlMemory

Also do a sanity check to make sure the memory region is free for linear allocations

* Memory: Make TLS only 0x200 bytes for each thread

Also move TLS to Base region

* RO: Unmap CROs when unloaded

Thanks @noumidev

* Kernel: Return used app memory for Commit ResourceLimit

Not quite correct, but nothing to be done until process management is improved
Also remove the stack limit for CXIs (thanks amogus)

* Kernel: Report used app memory for GetProcessInfo 2

Not really correct, but it should be accurate for applications at least

* Formatting changes

* Initial fastmem support

* PCSX2 fastmem depression

* Move away from PCSX2 fastmem

* Add enum_flag_ops.hpp

* Finally building on Windows

* Almost got a PoC

* Fix arm64 builds

* This somehow works

* This also works...

* Properly fix fastmem

* Add free region manager

* Update boost

* Add ScopeExit

* Comment out asserts on Linux/Mac/Android

* Comment out ASSERT_MSG asserts too

* Fix derp

* Attempt to fix Android

* Disable fastmem on Android

* Fix Android again maybe pt 2

* android pls

* AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA

* AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA

* Update host_memory.cpp

* Properly reset memory arena on reset

* Proper ashmem code for Android

* more

* Add temporary Android buildjet script for faster prototype builds

* Fix fastmem (again)

* Clean up shared memory

* Remove Android BuildJet runner

* a

* Revert "a"

This reverts commit 5443ad6f2a794c19c9b1a1567ca1c7f58eed78cd.

* Re-add ELF support

* Re-add 3DSX support

* GetSystemInfo, GetProcessInfo: Memory sizes should be in bytes

* Update Boost

* Update metal-cpp

* Fix metal renderer compilation

* Fix fastmem mapping

* Clean up fastmem code

* Fix oopsie again

* Emulator: Reorder struct

* Kernel types: Cleanup

* Cleanup

* More cleanup

* Make invalid mprotects warn instead of panicking

* Add setting for toggling fastmem

* More cleanup

* Properly initialize BSS to zeroes

* Remove unused code

* Formatting

* Cleanup

* Memory/CRO: Workaround for Pokemon XY

* NCSD loader: Fix BSS (again)

* NCSD loader: Fix BSS (again) (again)

* More memory fixes

* Memory: Remove unused code

* FS: Warn on unimplemented functions instead of panic

* Update software_keyboard.cpp

* Libretro: Add fastmem option

* FRD: Stub SaveLocalAccountData
