fix(a380x): missing tooltip declarations

[LelouchTwT]

Fixes #9214

Summary of Changes

I corrected the missing tooltip declarations in the LOK file, updated the autobrake tooltips key to match the LOK file, and created a new tooltip for the button that switches from true heading to magnetic. Previously, it was incorrectly using the "AP ENGAGE" tooltip.

Screenshots (if necessary)

References

Additional context

The autobrake tooltips, except for RTO, were referencing a mismatched key in the LOK file.
Tooltips for the AUTO signs were undefined.
I overwrote the ENG 1 and ENG 2 de-ice tooltips because they were labeled as left and right engine de-ice.

Testing instructions

The updates I made are purely visual. You only need to hover over the buttons to see the tooltips. There are different tooltips for each state.

Hi, that COCKPIT.TOOLTIPS prefix is from the fs-base package that is part of the base sim and we should not define any keys with that prefix. All of the new tooltips should follow the RMP example and use a name like A380X.TOOLTIPS.<system>_<item>_<tooltip type>. The tool top type is TITLE or ACTION where TITLE is “PANEL LIGHTING BRIGHTNESS” in this pic and ACTION is “Adjust panel lighting brightness”.
