QtQuick: clean up shader effect property connections
- Don't use a signal mapper, but handle the mapping using a custom slot
object and a lambda to do the dispatching ourselves.
- Don't do meta-calls by property name, but by index.
- Cache the meta-object.
- Resolve the property indices by using the QML property cache.
For a shader with 6 property connections, the time spent goes from 320k
instructions to 80k instructions (valgrind on x86_64).
Task-number: QTBUG-53901
