[Ozone] Rename and split the DRI platform for clarity

This CL does the following:
 - Moves the files in ui/ozone/platform/dri to ui/ozone/platform/drm
   since the platform name should really be DRM rather than DRI. Note,
   that the platform is still refered to as "dri" in GYP/GN since CrOS
   builds are still using the 'dri' name.
 - Rename all files with a "_dri*" suffix to a "drm_" prefix. Also
   rename all files with a "dri_" prefix to a "drm_" prefix.
 - Rename NativeDisplayDelegateDri to DrmDisplayDelegateManager since it
   is no longer dependent on the NativeDisplayDelegate interface and the
   new name better describes its intent.
 - Split the files in the platform into 2 sub-folders ("host" and
   "gpu"). Depending on the intended use place of the objects (Browser
   (host) process or GPU process) the files in the platform are split
   accordingly in the 2 sub-folders.
