Move the macro definitions for Q_DECL_UNUSED_MEMBER along with
a definition for Q_DECL_UNUSED from the scope excluding icc
and cl into a separate one for plain clang and cl since the
attributes work with clang-cl as well.
Remove the check introduced in
9782938045
since it is assumed that all clang versions have the attribute now.
Fixes:
