Add dedicated HLE delay/eat cycle funcs

And also remove the Puyo Puyo Fever hack.  I don't think it's needed anymore (after scheduling fixes), and I'm worried it could be causing issues (e.g. like the vCount and hCount stuff recently...)

Anyway, that fixes the display/vblankmulti test.

This also delays `sceUtilityLoadAvModule()`.  None of my games seem to care but it may matter since `sceUtilityLoadModule()` did.
