Currently the build flag for the ozone platform DRM is actually ozone_platform_gbm. This change renames this flag to ozone_platform_drm in a backwards compatible way. This change will also require changes to third_party in order to support the deprecation of the old flag. (see https://crbug.com/1122010) The final act of this rename will be to remove the old flag.
