Build clients without dynamic library dependencies on Android

We need to modify the CMake scripts to build all client libraries using only static dependencies (static runtime libraries and the *_static variants of DR extension libraries) on Android.
This should be the default behaviour on Android and possibly optional (but not default) on other platforms.

Doing this will allow us to proceed with Android support without needing to fix the private loader first (#3543).
