fix(core): use synchronous asset loading for AOT metadata (#630)

LoadMetadataForAOTAssemblies used LoadAssetAsync + await per file,
causing N+ frames of unnecessary delay during initialization. Since
this runs before gameplay, synchronous loading is safe and eliminates
the frame-per-file overhead.
