fix: don't throw compilation errors for `emitEvent` function for RN < 0.72

[kirillzyusko]

📜 Description

Fixed compilation errors on RN 0.71 and keyboard-controller 1.12.

💡 Motivation and Context

emitDeviceEvent is available only in RN 0.72 and we don't want to support RN 0.72 as the minimal version (because it's still quite new):

The original change was introduced in https://github.com/kirillzyusko/react-native-keyboard-controller/pull/410 - it was needed because old implementation threw errors (crashes) in bridgeless mode on Fabric.

In this Pr I made it compatible with bridgeless + it doesn't use newly introduced methods, so it should have a support until RN 0.65 again.

📢 Changelog

Android

• don't use emitDeviceEvent as it's available only in RN 0.72;
• revert to previous code variant, but send an event from ReactApplicationContext class instance;

🤔 How Has This Been Tested?

Tested on Pixel 7 Pro (Android 14), Fabric + RN 0.74

📝 Checklist

• [x] CI successfully passed
• [x] I added new mocks and corresponding unit-tests if library API was changed
