This change completes support for import assertions for dynamic import(). A new version of the HostImportModuleDynamically callback taking import assertions is added to the public API. The name is very verbose; we could consider removing the "ImportAssertions" part when the old API is removed. Bytecode generation is updated to pass the assertions, if present, to Runtime_DynamicImportCall. Isolate::RunHostImportModuleDynamicallyCallback extracts the assertions from the options bag, filters out the assertions not present in the list specified by the host in HostGetSupportedImportAssertions, and sorts them by code point order of the keys per https://tc39.es/proposal-import-assertions/#sec-import-call-runtime-semantics-evaluation. The resulting array is passed to the host in the callback.
