Ben Wagner 3d9ab7e7ec Separate general defaults from Skia defaults
In the build there are some defaults which actually apply to every
use of a built-in target type, but there are some (particularaly
warnings) which apply only to targets controlled by Skia. Currently
these unwanted defaults are magically known to exist and removed
wherever they are not wanted. Instead, create 'skia_' prefixed target
templates and apply these defaults to those instead.
