Valentin Shergin df4521e6c4 Fabric: Making jsi::Runtime a part of EventBeat and EventPipe
Summary:
We double down on JSI in Fabric. So, practically, JSI is now a hard dependency for Fabric. I hope it's for good.
Now `jsi::Runtime` is coupled with scheduling via `EventExecuter`, so we have to make `jsi::Runtime` a part of `EventBeat` to proxy runtime reference to bindgings.
