TextToSpeech: make engine parameters available from QML

Add a map-type property that QML code can initialize to engine-specific
key/value mappings. Changing the property at runtime re-initializes the
engine.

Implement asnychronous initialization option in the mock engine so that
we can test those code paths better.
