Q(Plain)TextEdit: Add find() overload with QRegExp

Add overloads to the find() methods in QPlainTextEdit and QTextEdit
that find the next occurrence matching the passed regular expression.

These are convenience methods that eliminate the need to use the
document() method and the need to handle the QTextCursor return value.
