Re-register dumpables for Region Sampler

Re-registering dumpables on top of ClockEventController fix (change-id: I7568f0c096e0f3759b3ee82347cfbda2f4d66132) so that we can see
state of Region Sampler in places where it's implemented (lockscreen
smartspace and clock).

Bug: 202758428
Test: manual
Change-Id: I644957e2e1c2a4b15d43b839aa609cf9884b9da9
