Add support to IVirtualMemoryManager for zero-copy reads (#6251)
* - WritableRegion: enable wrapping IMemoryOwner<byte>
- IVirtualMemoryManager impls of GetWritableRegion() use pooled memory when region is non-contiguous.
- IVirtualMemoryManager: add GetReadOnlySequence() and impls
- ByteMemoryPool: add new method RentCopy()
- ByteMemoryPool: make class static, remove ctor and singleton field from earlier impl

* - BytesReadOnlySequenceSegment: move from Ryujinx.Common.Memory to Ryujinx.Memory
- BytesReadOnlySequenceSegment: add IsContiguousWith() and Replace() methods
- VirtualMemoryManagerBase:
  - remove generic type parameters, instead use ulong for virtual addresses and nuint for host/physical addresses
  - implement IWritableBlock
  - add virtual GetReadOnlySequence() with coalescing of contiguous segments
  - add virtual GetSpan()
  - add virtual GetWritableRegion()
  - add abstract IsMapped()
  - add virtual MapForeign(ulong, nuint, ulong)
  - add virtual Read<T>()
  - add virtual Read(ulong, Span<byte>)
  - add virtual ReadTracked<T>()
  - add virtual SignalMemoryTracking()
  - add virtual Write()
  - add virtual Write<T>()
  - add virtual WriteUntracked()
  - add virtual WriteWithRedundancyCheck()
- VirtualMemoryManagerRefCountedBase: remove generic type parameters
- AddressSpaceManager: remove redundant methods, add required overrides
- HvMemoryManager: remove redundant methods, add required overrides, add overrides for _invalidAccessHandler handling
- MemoryManager: remove redundant methods, add required overrides, add overrides for _invalidAccessHandler handling
- MemoryManagerHostMapped: remove redundant methods, add required overrides, add overrides for _invalidAccessHandler handling
- NativeMemoryManager: add get properties for Pointer and Length
- throughout: removed invalid <inheritdoc/> comments

* make HvMemoryManager class sealed

* remove unused method

* adjust MemoryManagerHostTracked

* let MemoryManagerHostTracked override WriteImpl()

Refactor memory managers to a common base class, consolidate Read() method logic (#6360)
* - add new abstract class `VirtualMemoryManagerBase`
- rename `MemoryManagerBase` to `VirtualMemoryManagerRefCountedBase` and derive from `VirtualMemoryManagerBase`
- change `AddressSpaceManager`, `HvMemoryManager`, `MemoryManager`, and `MemoryManagerHostMapped` to implement abstract members and use the inherited `void VirtualMemoryManagerBase.Read(TVirtual va, Span<byte> data)` implementation.

* move property `AddressSpaceSize` up by the other properties

GPU: Remove CPU region handle containers (#4817)
* GPU: Remove CPU region handle containers.

Another one for the "I don't know why I didn't do this earlier" pile.

This removes the "Cpu" prefixed region handle classes, which each mirror a region handle type from Ryujinx.Memory.

Originally, not all projects had a reference to Ryujinx.Memory, so these classes were introduced to bridge the gap. Someone else crossed that bridge since, so these classes don't have much of a purpose anymore.

This PR replaces all uses of CpuRegionHandle etc to their direct Ryujinx.Memory versions.

RegionHandle methods (specifically QueryModified) are about the hottest path there is in the entire emulator, so there is a nice boost from doing this.

* Add docs
