[gui] Improve result highlight in Usage and Search dialogs

[skylot]

Now for highlight search result in Usage dialog used text search in code line, but jadx knows exact node place and should use that info to correctly highlight code.
Same approach should be used in Search dialog for Class/Method/Field nodes search.

This issue created from discussion started in #2006.

@MrIkso not sure why you decided to redone UI, because this issue is more about highlighting in code view for usage dialog and only partially in search dialog. And #2373 is just fixing resource name.

Anyway, main focus in table version of UI was on code view, because often class names are obfuscated and don't help in understanding code logic. So I don't think such rework is really needed, I suggest opening a draft PR for this change, maybe someone else will share another opinion or suggestion.
