Remove some superfluous //ui/gfx includes from //components headers

With the exception of ui/gfx/color_utils.h, code in //ui/gfx use
namespace gfx, so if "gfx::" does not appear in a header, then it does
not need the //ui/gfx includes. The command below generated the list of
edited files:

git grep -l '^#include "ui/gfx' components|grep '\.h$'|xargs grep -L gfx::

Clean up those headers and then do IWYU to fix the build.
