Add intrinsics on light greylist

Put intrinsics which are hidden API on light greylist. These were
implicitly considered white so far, so we would not have seen warnings
about their uses and should greylist them for P.

Note that these have been greylisted before in CL
I8fba27a529a83751ab27859b1c1b791ab85786cf but the CL was reverted.
