Autolinking on Android doesn't like hyphens in library name

And renamed import to match as well, though don't know why needed the folder name before. Plan to drop the subfolders from cpp folder

There's no need for the subfolders now that React Native autolinks on android. The subfolders were to make the handwritten setup on android more consistent

This reverts commit ca6288f.

Copying code from react native's autolinking example troZee/react-native-cpp-autolinking@5e1b0f2

Copied it from the codegen'ed one and pointed LOCAL_SRC_FILES at both the codegen and the hand-written c++ state files in cpp folder. Just a first go, not tried it yet

Don't know why it's needed as well as Android.mk?! Copied the codegen'ed one and added codegen files and c++ state cpp files

Couldn't get it to work using codegen and cpp folder - so followed advice from reactwg/react-native-new-architecture#71 (comment) that said needed own c++ implementation for everything. Gets further but falling over at the NativeMaterial3ModuleSpec - it's not generated now. Wondering if this approach works with ModuleSpecs as well?!

This file was codegen'ed but clearer to drop the 'generated' from the name

Copying from react native autolinking repo and they only have the CMakeLists.txt troZee/react-native-cpp-autolinking@5e1b0f2

Need to put together example repo with android build failing so react native can investigate

Had to go through all the files on the example repo 1 by 1 to see what was wrong, JSI_EXPORT. There were 3 key errors
1. Added JSI_EXPORT to hand-written cpp interfaces
2. Include "Props.h" instead of <react/renderer/components/navigationreactnative/Props.h>
3. Removed libraries from codegenConfig in package.json
These each took me ages to spot

Also went back to androidMkPath because cmakeListsPath is a later change. Copies the config from React Native's autlink example

Copying over the codegen didn't work for ios. Ended up with redefinition of EventEmitters errors reactwg/react-native-new-architecture#71 (reply in thread). There's no custom build on ios so it includes the copied over codegen as well as the actual codegen so it gets included twice. Can't just exclude it on ios because the includes on shadownodes point to local "EventEmitters.h'.
So went with the react native screens approach of pointing at the codegen instead of copying it over reactwg/react-native-new-architecture#71 (comment). It works on android and should work on ios (haven't tested yet) because it's just the hand-written files now

Copied this over from react native screens example but isn't necessary

This matches approach for generated components

The current directory has no relevant cpp files - they're now all in react/renderer/components/navigationreactnative

Still copying code from react native screens example reactwg/react-native-new-architecture#71 (comment)
Couldn't work out how to get the ComponentDescriptor in the generated rncli.cpp because it only includes ComponentDescriptors.h. Noticed it also includes navigationreactnative.h - so the trick is to include the hand-written descriptors in that file!! React native screens did this just didn't notice or realise what it was for. It's very sneaky!
This allows it to work on android and ios!! And with lower maintenance because not copying over hand-generated - apart from navigationreactnative.h and .cpp. Had to exclude these files from the podspec otherwise doesn't build on ios
