Bartek Nowierski deb7584e0d Remove ExperimentalAsh trait usage from ash/*
The trait was used to select pointers for the BRP experiment. BRP is
now fully enabled for Ash, and the experiment is no longer necessary.

Semi-automated via magic of search+replace:
 - " | ExperimentalAsh" -> ""
 - ", ExperimentalAsh" -> ""
 - "ToRawRef<ExperimentalAsh>" -> "ToRawRef"

This CL is a no-op.
