Anand Thakker b5b4549b6d Fix edge case in composite function interpolation (#8613) ...

This fixes a bug where, for a zoom value greater than that of the highest zoom
stop, composite function interpolation would return nan. (Blocking a render
test over in #8593)

* Add failing tests for composite function edge case

The failing cases here are:
 - Should interpolate before the first stop
 - Should interpolate past the last stop

* Fix edge case in composite function interpolation

* Hold functions constant outside stop-defined domain
