refactor gradient stage names
This is just a name refactor and I'm happy to delay it until we're done
with the current wave of gradient CLs. The main ideas:
- we use the "linear_gradient" stages for all gradients,
so cut the "linear" and just call them "gradient";
- remind ourselves that the 2-stop stage requires even spacing, i.e.
stops at 0 and 1. This name should harmonize with Herb's new
general evenly spaced gradient stage, currently
"evenly_spaced_linear_gradient", and after it lands and I rebase,
"evenly_spaced_gradient"
- remind ourselves which polar coordinate xy_to_polar_unit returns,
the angle.
