Move Chromoting strings to string_resources.grd and simplify remoting_resources target.

Previously all strings were in messages.json files. Moving them to GRD
file will allow to share them with native components. Also simplified
how resources are generated:
 1. Now <if> is used to handle branded strings instead of generating
    grd file in build time
 2. Removed resource_ids - ids are now specified in grd files.

BUG=158995
