remove dependency of Android NDK and all forms of C/C++ code

liblouis, the only braille translator, is in C and depends on Android NDK (for native code) to build Talkback

https://github.com/talkback-foss-team/talkback-foss/tree/main/braille/src/main/jni

That needs to be replaced with something else that does not use C.

Not a high priority.

If not, someone experienced in C needs to take a look at the code as it's highly unmaintained and there is a lot of memory safety concerns in it, something GrapheneOS's hardened_malloc would catch.

It needs to be tested properly too with Braille.

Would be glad to see liblouis rewritten in Kotlin, Java or at least Rust.

Seams we should watch for Liblouis updates as most of the last version changes are those regarding memory corruptions / leaks.
