[FEATURE REQ] `ReadOnlyMemory<byte>` overload for `AppendBlobClient`.`AppendBlockAsync`

[Peter-Juhasz]

Library name

Azure.Storage.Blobs

Please describe the feature.

There is only a Stream overload for AppendBlockAsync, and while we can have a pool of MemoryStream instances, it is far from the best choice for high performance scenarios (e.g. writing some kind of log entries to an append blob - which may be a common scenario).

An overload with ReadOnlyMemory<byte> to avoid allocations and copying would be great. Also, an BinaryData overload to be consistent with modern .NET.
