RJS-2888: Fixing React scheduler's call to RN CallInvoker's invokeAsync and upgrading our RNTA test app to React Native v0.75.1

[kraenhansen]

What, How & Why?

This closes #6845 and #6846 by updating RN specific scheduler to use a backwards compatible call signature for CallInvoker's invokeAsync.

A bit more context on the proposed changes

React Native's CallInvoker API changed with facebook/react-native#43375, such that the func callback argument now takes a jsi::Runtime. This was first released as react-native@0.75.0.

Care was made in that PR to provide signatures for backward compatibility, but these were only added for overload that doesn't take a SchedulerPriority as first argument (which we depend on). As I see it, we have a few ways forward:

1. Upstream a fix to RN adding the missing backward compatibility overloads.
2. Fix the callback we pass to take a jsi::Runtime argument.
3. Call the backwards compatibility overload that doesn't take a SchedulerPriority (without a jsi::Runtime in the func).

Option 1 will leave realm broken for 0.75.0 and 0.75.1 forever and depends on the grace and a hotfix from the React Native team to be immediately effective. Option 2 will make the coming release of realm backwards incompatible with react-native prior to 0.75.0 which would be very unfortunate and could potentially require a major version bump on our side. I believe our best option now is 3, as that will alleviate the immediate issue fast and good compatibility, although we'll be providing less context when calling into the call invoker.
