Bug 1877792 - Part 9: Add module type to ModuleLoaderBase::{CreateStaticImport,CreateDynamicImport} r=spidermonkey-reviewers,dom-worker-reviewers,dom-core,asuth,jonco,mccr8

This patch adds a module type parameter to
`ModuleLoaderBase::{CreateStaticImport,CreateDynamicImport},` and gets rid of a
bunch of hard-coded `JS::ModuleType::JavaScript.` However, the module type is
still hard-coded when we call `CreateDynamicImport` and `CreateStaticImport`.
