Sathya Gunasekaran e101b9c03c [parser] Improve error when using import decl in a script
Perform a best-effort check for module context and provide an
appropriate error.

As seen from the import-blah-script.js test, we could have invalid
import expressions in a script context that could result in an error
saying "Cannot use import statement outside a module" which isn't
the ideal error because the error is an incorrect import
expression.

But, when the developer changes to a module context, the
correct error is thrown.

To fix this, we'd have to refactor and call ParseImportDeclaration,
and then throw an appropriate error, which seems like a lot of
overhead for not enough gain.
