Fix loading of ES modules when using CONFIG += qtquickcompiler

Added the missing lookup for cached .mjs files in
ExecutionEngine::compileModule. This allows using .mjs files in
WorkerScript {} elements in conjunction with the Qt Quick Compiler and
also fixes the use when using QJSEngine::importModule.

[ChangeLog][QtQml] Fix loading of EcmaScript modules when using the Qt
Quick Compiler.
