2654a679b3 Memory: replace PhysicalToVirtualAddress with a more dedicated function 
There is no external use of PhysicalToVirtualAddress any more, so it there is no need to have a generic function that handles all physical regions. Also, the previous APT change makes it possible that linear heap has some regions mapped to old and new VAddr regions at the same time, so we need to check both region and mark cached for the mapped one. RasterizerMarkRegionCached would skip the unmapped one in its loop

Kernel: reimplement memory management on physical FCRAM (#4392) 
* Kernel: reimplement memory management on physical FCRAM

* Kernel/Process: Unmap does not care the source memory permission

What game usually does is after mapping the memory, they reprotect the source memory as no permission to avoid modification there

* Kernel/SharedMemory: zero initialize new-allocated memory

* Process/Thread: zero new TLS entry

* Kernel: fix a bug where code segments memory usage are accumulated twice

It is added to both misc and heap (done inside HeapAlloc), which results a doubled number reported by svcGetProcessInfo. While we are on it, we just merge the three number misc, heap and linear heap usage together, as there is no where they are distinguished.

Question: is TLS page also added to this number?

* Kernel/SharedMemory: add more object info on mapping error

* Process: lower log level; SharedMemory: store phys offset

* VMManager: add helper function to retrieve backing block list for a range

13606a6d0b Memory: Remove count of cached pages and add InvalidateRegion 
In a future commit, the count of cached pages will be reintroduced in
the actual surface cache. Also adds an Invalidate only to the cache
which marks a region as invalid in order to try to avoid a costly flush
from 3ds memory

d553135748 Memory: Add function to flush a virtual range from the rasterizer cache 
This is slightly more ergonomic to use, correctly handles virtual
regions which are disjoint in physical addressing space, and checks only
regions which can be cached by the rasterizer.

Also add a bunch of forgotten transitive includes, which otherwise

d192fb066d Kernel/Threads: Dynamically allocate the TLS region for threads in the BASE region of the linear heap. 
Each thread gets a 0x200-byte area from the 0x1000-sized page, when all 8 thread slots in a single page are used up, the kernel allocates a new page to hold another 8 entries.

This is consistent with what the real kernel does.
