Replace and remove obsolete ByteMemoryPool type (#7155)

* 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`
