mojo: snippets-internals: Use new bindings names in snippets-internals

Mojo JS Lite Bindings were recently renamed to align with the new C++
names. This CL changes usage of the old names with the new ones. See
bug for more details.

Also adds snippets_interals:closure_compile to the closure_compile
target so that type checks are run.
