Use pooled memory and avoid memory copies (#6691)

Browse source 
* perf: use ByteMemoryPool

* feat: KPageTableBase/KPageTable new methods to read and write `ReadOnlySequence<byte>`

* new: add IWritableBlock.Write(ulong, ReadOnlySequence<byte>) with default impl

* perf: use GetReadOnlySequence() instead of GetSpan()

* perf: make `Parcel` IDisposable, use `ByteMemoryPool` for internal allocation, and make Parcel consumers dispose of it

* remove comment about copySize

* remove unnecessary Clear()
