Add a "Cyclic" gradient option that closes the ramp into a seamless loop (#4416)

Browse Source 
* Add a Cyclic gradient attribute that wraps the stop list through the 1|0 boundary back to the first stop

* Show the wrap segment's midpoint diamond in the color picker spectrum strip when cyclic

* Keep the wrap midpoint diamond tracking the pointer by a wrapped strip width when dragged past the ends

* Give the Gradient tool's viewport overlay the same cyclic wrap midpoint diamond and drag behavior

* Correct the docs claiming the final stop's midpoint is always ignored now that cyclic uses it

* Move the gradient cyclic toggle onto the Ends row as a Link icon checkbox

* Update labels

* Register GradientHueDirection with the Data panel so its attribute column renders

* Reword wrap segment to wrapped interval and stray segment usages to interval

* Clean up comments

* Fix the color picker write-back losing default position elision and the blend path guessing the cyclic flag
