Find VBA-only functions when compiling first on module level

Find VBA-only functions when compiling first on module level

This likely never worked as there is no SbiInstance in that step,
but worked by chance when running a module's code that was
compiled with VBA support where the VBA-only function was added as
a symbol to be resolved later during runtime and then the
SbiInstance exists and the symbol was magically resolved.

Found when trying to correct vba_tests to actually fail if all
subtests fail that then started to fail in Atn.vb because of the
Round() function being VBA-only.
