Remote Layer Tree: Support hardware accelerated filters

[Tim Horton]

I took the approach of serializing FilterOperation and FilterOperations and using existing PlatformCAFiltersMac code to apply them on the UI process side.

I haven't added custom filter support yet, that might be slightly more tricky.

Actually it looks like we don't have accelerated custom filters so we don't need this.

I think FilterOperation should be a const reference.

Can use std::move(filter) here to avoid ref churn.
