Remove JS natives support, step 2

The natives blob is deprecated and will be removed in the next
release.

Step 1 landed in https://crrev.com/c/1824944.
Step 2 (this CL) is to mark API functions as V8_DEPRECATED.
Step 3, in the next V8 release, is to remove these functions and all
other natives support in V8.
