RSDK-8061 meta-in-tarball for local android development

[abe-winter]

What changed

• use meta-in-tarball for local android development (new pattern) instead of side-by-side meta.json (old pattern)
• update docs

Why

Meta-in-tarball is cleaner (single file to deal with) and we want to deprecate side-by-side eventually.

Testing

Tarball has meta.json as expected:

$ tar tf module/build/outputs/module/debug/module.tar.gz 
meta.json
mod.sh
module.jar

File gets copied correctly:

$ ./gradlew pushModuleAdbDebug

> Task :module:stripDebugDebugSymbols
Unable to strip the following libraries, packaging them as they are: libjingle_peerconnection_so.so.

> Task :module:pushModuleAdbDebug
