Introduce new qt-shell and an API for custom shells

Adds a new API for writing custom shell extensions. This API is supported,
but semi-public. Binary compatibility is not guaranteed.

Also adds qt-shell, a new shell that maps directly to the QWindow API, and
provides functionality that Qt provides on other window systems, such as
absolute window positions and window activation. This shell is not intended
for use on the desktop.
