This PR implements the use of multi frame editing falloff for the
transform tools in GPv3. When 'Use Falloff' is enabled in the
Multiframe panel, the extent to which the transform tool is applied to
the selected frame is determined by the falloff curve.
All transform tools are supported: move, rotate, scale, change radius,
bend and shear.
The falloff also works when combined with Proportional editing.

This is a bug fix also submitted separately: #120870: Fix: GPv3: Incorrect multi frame falloff factor due to miscalculation in frame range.
It's in this PR to be able to test the functionalities.
