GN foreach should mark the list identifier as used.

GN foreach should mark the list identifier as used.

Previously an identifier used as the list in a feoreach statement would not count as "using" the identifier, which would give unused variable errors. Added a unit test.

Checks for unused identifiers in component(). Previously these were not checked. This checking turned up a misspelling in the cc build. Added a unit test.

Fixes for the ozone media build (turned up when testing).
