debugger: Fix RecursionError when fetching Qt version

Browse Source 
When working with statically linked Qt qVersion may not be available.
In that case Qt uses the qtHookData which has type of quintptr.
This type is subject to SyntheticChildrenProvider because lldb
hooks are set up via a regular expression.

When SyntheticChildrenProvider is instantiated, it tries to fetch
Qt version, which causes another instantiation which again recurses.

The fix is to bypass SyntheticChildrenProvider via GetNonSyntheticValue.
