Instead of hard coding paralyze this makes the code extensible to possible
future sticky modes

The vtx code doesn't have a lot of test coverage, so this adds a basic unit test that asserts vtx pit mode behavior

On bootup aux channels start out at default and allow sticky modes right away,
although they should only be allowed once they are actually not active.

When the separate rc rates and rc expos for roll/pitch were added the descriptive names were never added to the OSD display strings array. Then later PID audio was added causing the array to be out of sync with the enumerated adjustment types. This led to a corrupted pointer reference in the OSD display.
Also the adjustment display name used for the OSD display was never initialized so the pointer was pointing to random memory.
Removed the use of globals and changed to use "getter" functions.
This allows modes to be linked, for example to link vtx pit mode to paralyze. Whenever paralyze is activated, vtx pit mode is activated as well. Also the logic to prevent mode changes when enabling paralyze can be removed in favor of making paralyze sticky.
Modes can be linked in CLI by providing the mode id as the last parameter of the aux command. For example in order to link vtx pit mode to paralyze, replace the last 0 of the pit mode aux (39) with the mode id of paralyze (45):
```
aux 2 39 2 1700 2100 0 0
```
becomes
```
aux 2 39 2 1700 2100 0 45
```
