Introduce findTextFinished signal

This is a replacement for the callbacks. Also introduces
QWebEngineFindTextResult class what is common for the Quick and Widget
APIs. This makes possible to provide extra information about the match,
eg. the number of matches and the index of the currently highlighted match.

signal and FindTextResult type to provide extra information about the
result of a text search.
