Remove libdazzle dependency

Merged Maximiliano requested to merge msandova/gtranslator:dazzling into master

The part which handled the search options had to be refactored to both drop libdazzle and be portable to GTK 4.

Marked as draft as I am still have to restore the GtkSearchEntry::search-stop functionality.

In order to add the entry popover I had to refactor a nice chunk of code, but I think its for the better, I don't even know how the previous code even worked.
