Replace and remove obsolete ByteMemoryPool type (#7155)1.1.1372
* refactor: replace usage of ByteMemoryPool with MemoryOwner<byte> * refactor: delete unused ByteMemoryPool and ByteMemoryPool.ByteMemoryPoolBuffer types * refactor: change IMemoryOwner<byte> return types to MemoryOwner<byte> * fix(perf): get span via `MemoryOwner<T>.Span` directly instead of `MemoryOwner<T>.Memory.Span` * fix(perf): get span via MemoryOwner<T>.Span directly instead of `MemoryOwner<T>.Memory.Span` * fix(perf): get span via MemoryOwner<T>.Span directly instead of `MemoryOwner<T>.Memory.Span`
