Summary:
So, this makes it so a set of behaviors that require accessing java can be injected from the jni/ folder. The behaviors are logging, perf logging, log markers and loading script from assets.
I'd argue that these should all actually be encapsulated by interfaces that are passed to the JSCExecutor/others (and I'd say that's regardless of whether they are injected from jni/ or not), but I wanted to stick to the least disruptive pattern for these changes.
