Adding all necessary for UR code offline signing in both directions
and needs to get enabled with `WITH_OTS_UR` to compile with UR.
This update depends on [monero
PR](https://github.com/monero-project/monero/pull/9492).
It cannot work without modifications on monero core!
@tobtoht also mentions that build with static Qt5 will not
work. I compiled and tested exclusively with ubuntu 24.04
in Qt Creator with Qt 5.15.2
CAUTION: Do not merge before monero PR #9492 is merged!
