* - 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()
