Bug 1556012 [wpt PR 17117] - Add support for timing functions jump-start|end|both|none., a=testonly

Automatic update from web-platform-tests
Add support for timing functions jump-start|end|both|none.

Jump-start is equivalent to start, with a discontinuity at t = 0.
Jump-end is equivalent to end, with a discontinuity at t=1.
Jump-both has discontinuities at t=0 and 1.
Jump-none is continuous at t=0 and t=1.

The patch also addresses some serialization issues with existing
step functions since the code needed to be updated in support of the
new step types.
