The JavaScript/TypeScript bindings don't support engine config parameters

Unless I'm not seeing it, the JavaScript/TypeScript interface doesn't support the ability to pass in engine and driver configuration parameters. We need to modify those values to handle the larger scene sizes we regularly encounter.

The parameters I'm referring to are the `filament::Engine::Config` struct values:
- commandBufferSizeMB
- perRenderPassArenaSizeMB
- driverHandleArenaSizeMB
- minCommandBufferSizeMB
- perFrameCommandsSizeMB

The only engine creation options I see are for GL settings.

Thanks.
