[C#] Added ToSizedArrayPadded(int padLeft, int padRight) to ByteBuffers to avoid unnecessary copying. (#8658)

Browse Source 
* Added ToSizedArrayPadded(int padLeft, int padRight) + ToArrayPadded(pos, len, padLeft, padRight) to the byteBuffers.
This is for API completion and to avoid unnecessary copy when framing my packets. I needed this to create a flat buffer with space in front of it for header / metadata.

* Fix indentation
