Added CreateArchToSharedObjectsMapTask.

[priettt]

Goal

This is one of the 4 tasks NdkUploadTask will get separated into.

This task receives a directory with architectures as its input, and outputs a map of each architecture to a list with every shared object file path of that architecture.

For instance, if the input directory is this:

archs 
| - - - - armeabi-v7a
             | - - - - libtest1.so
             | - - - - libtest2.so
| - - - - arm64-v8a
             | - - - - libtest3.so
             | - - - - libtest4.so

The result will be this map:

armeabi-v7a -> [path to libtest1.so, path to libtest2.so]
arm64-v8a -> [path to libtest3.so, path to libtest4.so]

I also moved the logic to find the architecture directories to the task registration, so it's passed as a provider to the task.

Testing

Added an integration test for the task, still need to test the registration.

I didn't realise we were doing Zstd compression on SO files. IMO it'd be worth breaking that into a separate task that takes the uncompressed SO files as an input and the compressed files as an output. Sorry for the confusion from our discussion yesterday

Suggested change

	architecturesToHashedSharedObjectFilesMap.get().asFile.outputStream().use { outputStream ->
	architecturesToHashedSharedObjectFilesMap.get().asFile.outputStream().use { outputStream ->

It'd be worth using a buffered stream here to improve perf

Are these todo comments new or were they present in the previous code that's been adapted into this source file?

[priettt]

these are new, I'm adding them so I can then think about any uncommon codepaths
