Change TPA rate and Breakpoint to Percentages for ease of understanding

[ChrisRosser]

Is your feature request related to a problem? Please describe

For newer pilots TPA rate and breakpoint are somewhat obscure. It's not always clear to them that throttle goes from 1000 to 2000 as this isn't really the case any more with Dshot.

TPA rate is clearer but might make even more sense as a percentage attenuation.

Describe the solution you'd like

Presenting TPA rate and TPA breakpoint as percentages (and perhaps converting to 1000-2000 behind the scenes) and adding a tooltip explaining TPA would resolve this problem.

1350 would become 35%. 0.65 would become 65%.

Describe alternatives you've considered

I don't see the need to change anything in BF I think this could just be a configurator tweak.
