[VPlan] Move predication to VPlanTransform (NFC). (#128420)
This patch moves the logic to predicate and linearize a VPlan to a
dedicated VPlan transform. It mostly ports the existing logic directly.
There are a number of follow-ups planned in the near future to
further improve on the implementation:
* Edge and block masks are cached in VPPredicator, but the block masks
are still made available to VPRecipeBuilder, so they can be accessed
during recipe construction. As a follow-up, this should be replaced by
adding mask operands to all VPInstructions that need them and use that
during recipe construction.
* The mask caching in a map also means that this map needs updating each
time a new recipe replaces a VPInstruction; this would also be handled
by adding mask operands.
