feat: Add console logging support for Frame Processors (#297)

* Try to log to console via runOnJS

* Call `console.log`

* Create custom `VisionCameraScheduler`

* Fix scheduler call

* Call with this

* Fix console setting

* Move J---- to `java-bindings`

* c++ style

* Android: 1/2 Create custom Scheduler

* Android: 2/2 Use custom Scheduler

* Don't use `runOnJS`, use `__callAsync` directly
