[compiler] Add lowerContextAccess pass

*This is only for internal profiling, not intended to ship.*

This pass is intended to be used with https://github.com/facebook/react/pull/30407.

This pass synthesizes selector functions by collecting immediately
destructured context acesses. We bailout for other types of context
access.

This pass lowers context access to use a selector function by passing
the synthesized selector function as the second argument.
