style: Disable NSCAP_FEATURE_USE_BASE

This is a relatively small code size regression (130k on windows and
macOS, 180k on Linux), for a few high confidence improvements in
speedometer 3. See link in the bug.

If this sticks, we can actually clean up a bunch of code, and eventually
unify RefPtr and nsCOMPtr. But I want this to be on the tree for a while
before doing more aggressive refactorings / actually removing the code.
