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.

This sketches out what a world without Chrome's GN configs would look like.
Instead of DEPSing in build/, we now host our own gypi_to_gn.py.
The symlink from skia/ to . lets us run gclient hooks when the .gclient file is in the directory above skia/ or inside skia/. That means we don't need gn.py anymore.
