Turn on flags to enforce SK_API.

These flags hide symbols that are not marked with SK_API when linked into a
shared library.  There's nominally no effect on static linking, but I'm
pretty sure the Mac linker takes some advantage of this too to run faster.

This makes component-build DM no longer link: it uses many non SK_API APIs.
Fiddle in contrast is just fine with our public APIs, so no need to restrict that.

It'll be fun finding out which of our other tools go which ways.
