Use the same version_code and version_name for remoting_apk as chrome…

…_apk

This CL:
- Changes remoting_apk in GYP so that it uses the same version_code and
  version_name as chrome_apk
- Declares new GN variables so that remoting_apk in GN can share the
  same version_code and version_name as chrome_apk. (CL which ports remoting_apk
  to GN is at https://codereview.chromium.org/1473713005/)
