Add support to IVirtualMemoryManager for zero-copy reads (#6251)1.1.1251
* - 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()
