DC: BUILD: Always disable SCUMMv7+ on Dreamcast (Bug#6008)

Browse Source 
With the recent v7/v8 changes in the SCUMM engine, trying to run a v7/v8
SCUMM game is not a nice user experience anymore, because the game just
won't fit in the limited default memory available on Dreamcast anymore.

This is also a problem for some other engines on this platform, but the
SCUMM engine being one of the most popular engines, quite a lot of users
end up burning a toast CD-R on their Dreamcast until they figure out
that only SCUMMv6 and earlier still work nowadays (with some limitations
too).  Disabling v7/v8 from the SCUMM engine plugin should also free up
some memory for a better experience with earlier SCUMM titles.

# XXX: Enabling SCUMM v7+ hasn't been useful on DC for many years (bug #6008),
# and may confuse users, since this is one of the most popular engines, so make
# sure that it won't be enabled (until a better backend capability requirement
# feature is implemented). This may also help SCUMMv6 and below behave better
# on this very memory-limited platform.
