Add new c++ helpers to ease usage of size prefixed FlatBuffers (#4626)

Browse Source 
It was missing some helpers when we choose to use
size prefixed FlatBuffers.

* Add general helper : GetPrefixedSize
* Add generated helpers :
 * GetSizePrefixedXXX
 * VerfifySizePrefixedXXXBuffer
 * FinishSizePrefixedXXXBuffer
