Make multicopter position control parameter descriptions more concise

[MaEtUgR]

Solved Problem

When working on #24041 I found that Kakute F7 runs out of flash so @sfuhrer told me easiest is to save on some parameter description strings. But I think does are not included in flash-contained builds.

Even though there is no effect on that particular build I think cleaning up is worthwhile.

Solution

I shortened the texts to contain the essential information but avoid language decorations.
