Support memory aliasing (#2954)1.1.110
* Back to the origins: Make memory manager take guest PA rather than host address once again
* Direct mapping with alias support on Windows
* Fixes and remove more of the emulated shared memory
* Linux support
* Make shared and transfer memory not depend on SharedMemoryStorage
* More efficient view mapping on Windows (no more restricted to 4KB pages at a time)
* Handle potential access violations caused by partial unmap
* Implement host mapping using shared memory on Linux
* Add new GetPhysicalAddressChecked method, used to ensure the virtual address is mapped before address translation
Also align GetRef behaviour with software memory manager
* We don't need a mirrorable memory block for software memory manager mode
* Disable memory aliasing tests while we don't have shared memory support on Mac
* Shared memory & SIGBUS handler for macOS
* Fix typo + nits + re-enable memory tests
* Set MAP_JIT_DARWIN on x86 Mac too
* Add back the address space mirror
* Only set MAP_JIT_DARWIN if we are mapping as executable
* Disable aliasing tests again (still fails on Mac)
* Fix UnmapView4KB (by not casting size to int)
* Use ref counting on memory blocks to delay closing the shared memory handle until all blocks using it are disposed
* Address PR feedback
* Make RO hold a reference to the guest process memory manager to avoid early disposal
