Debugger: pmr containers

Browse Source 
Added support for visualization of for `std::pmr` containers
(and more broadly containers with custom non-empty allocators).
The gotcha with pmr allocators in particular is that
unlike most allocators these are non-empty classes:
they contain a pointer to a memory resource.

Tested locally with CDB and GDB (MinGW).

Task number: QTCREATORBUG-30224
