[new compiler] Fix signal handlers on own properties

When compiling signal handler expressions we need to determine the parameters.
We first try to look up the signal in the base meta-object. For our own
QML type itself we don't have a meta-object yet and so we extract the information
about which parameters the signals have from the parsed AST's signal declarations.

For signal handlers on declared properties we need to "synthesize" the
signal (myPropertyChanged) as well, with an empty parameter list.
