The appearance of the checkmark icon used by the palette tool will be improved
by this change.

However note that the throbber is also using VectorIconId::CHECK_CIRCLE,
rendering it at 18dp. See the comment "This magic number matches the default
diamater plus padding inherent in the checkmark SVG." - since you're now using a
different SVG with a different pixel grid, you'll need to make sure that the
checkmark in the throbber still looks good. (You can do this by building and
running the views_examples_with_content_exe target; it looks like there is a
throbber example you can use.)

The solution may be to tweak the value of 18 used by the throbber, or it may be
that we'll need to keep ui/gfx/vector_icons/check_circle.icon as-is and have a
separate ash/resources/vector_icons/system_menu_check_circle.icon used by the
system menu and palette tool.
