Slayer's Cleaver does not force an eldrazi to block

[drmDev]

Report on forums: attacked with a creature equipped with Cleaver, and only blocked by a non-eldrazi when it needed to be blocked by an Eldrazi such as Wretched Gryff.

"Equipped creature gets +3/+1 and must be blocked by an Eldrazi if able."

I know right in the code we have a comment that the "must be blocked by an Eldrazi if able" is not handled yet due to requiring some overhaul of the combat framework to account for this.

// TODO: The effect does not work correctly yet, we need to do some chnanges to combat handling to fix this

Test passing now, was resolved in earlier commit.
