replace ByteMemoryPool usage in Ryujinx.Graphics (#7129)

* chore: replace `ByteMemoryPool` usage with `MemoryOwner<byte>`

* refactor: `PixelConverter.ConvertR4G4ToR4G4B4A4()` - rename old `outputSpan` to `outputSpanUInt16`, reuse same output `Span<byte>` as newly-freed name `outputSpan`

* eliminate temporary buffer allocations

* chore, perf: use MemoryOwner<byte> instead of IMemoryOwner<byte>
