Use composition size limit on repeating effects

Concatenate short repeating vibration patterns for PWLE and composed
primitives into a larger command to the vibrator HAL, making use of the
limits for compositions.

Add a check to find the best place to break down a large or repeating
PWLE waveform, preferably at amplitude zero, to avoid segmenting the HAL
commands on a high amplitude, causing a click effect.
