Pretty printers: Unify code for different allocators

Browse Source 
The code path for allocators other than
'std::allocator' does work for 'std::allocator' as well,
so unify this.

This also fixes the case of std containers when
'std::allocator' is used and the compiler flag
'-D_GLIBCXX_DEBUG' in place which results in size assumptions
that were made in the now dropped path to not be fulfilled,
thus leading to an incorrect display.

Fixes: QTCREATORBUG-22606
