Add a Renderer API to force skipping frames (#9313)

Browse Source 
* Add a Renderer API to force skipping frames

Renderer::skipNextFrames(size_t) can be used to force filament to
pretend the next N frames must be skipped. This is mostly useful for
debugging.

* Add DebugOptions to Settings

We still need to move the "Debug" features of gltf_viewer to this,
but this give us a framework to do it. 
Currently there is one debug option that allows to set a number of
frames to skip.

ViewerGui propose a button to skip 10 frames using this framework

* Update libs/viewer/src/Settings.cpp
