Prior to this commit, the Dyntopo panel was hardcoded to display as
faded if the current brush was the mask brush. This conflicts with the
common set of brushes which we do not support dyntopo for, which
includes many other brushes.
This commit changes the check to better indicate that certain brushes do
not support dyntopo. The scene-level settings can still be changed & the
detail flood fill operator remains functional even if the a different
brush is selected.
Additionally, the panel is no longer greyed out if the "Manual" option is
active.
