QByteArray: add {const_,reverse_iterator}, {c,}r{begin,end}()

Had to mark {,c,const}{begin,end}() inline, since they are, and mingw
complains about inconsistent dllimport attributes.

[ChangeLog][QtCore][QByteArray] Added rbegin(), crbegin(), rend(), crend(),
and reverse_iterator and const_reverse_iterator typedefs.

Task-number: QTBUG-25919
