Subject: meson: Convert CMake to Meson build infrastructure

Provide infrastructure to be able to build the uvc-gadget library as a
shared object and an executable which links against this as a dependency
to implment the reference 'uvc-gadget' application.

All existing cmake infrastructure is removed. This removes custom glob
support that was previously used by an early development for Android,
which is expected to be re-added later when required.
