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.

Don't instantiate repeating boilerplate item data in some
cases (such as large arrays).
This makes it necessary to access parent WatchItems in
a lot more cases than before and needs another separation of
WatchItem/WatchModel code to keep the dumper autotests
in a functional state.
For a plain std::vector<int> with 1 mio items this reduces
extraction time from more than 2 minutes to about 3 seconds.

then the MSYSTEM env. var is set and our Pythons set os.sep and

of those shells.
fromNativePath(str) then fails to convert '\' seprators embedded
in binaries since str.replace('/', '/') is a noop. The operation
we want here is to convert all '\' to '/' anyway so this is more
explicit regardless of any opinions on our choice to dynamically
vary os.sep and os.path.sep
