Debugger: Use direct memory instead of member access

This introduces a dumper types abstraction layer with classes
Dumper.{Value,Type,Field} wrapping either gdb.{Value,Type,Field}
or lldb.{SBValue,SBType,SBField} and uses it to move
to more direct memory accesses in the dumper implementation.

This way we can use duck typing for artificial intermediate
objects eliminating the need for {gdb.Value,lldb.SBValue}.cast()
in some case which are flaky in general and typically not
available in release builds.

As consequence QRegion and QVariant dumper work without debug
info now.
