Clean up SK_PICTURE_USE_SK_RECORD and SK_PICTURE_OPTIMIZE_SK_RECORD.

Clean up SK_PICTURE_USE_SK_RECORD and SK_PICTURE_OPTIMIZE_SK_RECORD.

This folds the code through as if they were defined, which is the explicit
state in both our build and Chrome's.

This leaves the EXPERIMENTAL_ and DEPRECATED_ hooks in to be cleaned up or
privatized later.
