Enabling USER_RESTRICTED on content process caused widevine DRM to fail for Amazon Prime, Netflix, Disney etc.
We still have uses of WMFDecoderModule::CanCreateMFTDecoder which are being hit in content process.

This is required because with a USER_RESTRICTED access token level for the
content sandbox, we can no longer use WMF directly.
