LibVT: Fix UTF-8 handling in OSC sequences

Browse source 
Previously, we would ignore bytes in the `0x80..0xff` range when parsing
OSC strings. This caused terminal titles and hyperlinks containing
non-ASCII characters to fail. Also added is extending the UTF-8 fail
functionality for C1 control codes, since we do not handle those.

Fixes #7377
