CONFIGURE: Removed useless ENGINE_WIP_ defines from config.h

This is a holdover from when it was going to warn on a per-engine basis.
This warning is now handled on a per-game basis with ADGF_UNSTABLE and
ADGF_TESTING.

It resulted in a lot of spam in config.h: a define for every single
engine and subengine that looks like this:
define ENGINE_WIP_SCUMM_7_8 false

It was not being used in-tree and I don't see it being used in the near future.
