Don't propagate deps across actions in GN.

This change makes library propagation stop at actions and copy rules. This
allows actions to take libraries as inputs without forcing dependants to also
link to them. It's not normal to have an action or copy rule where you want
to propagate such libraries.

Enhance the deps documentation to discuss propagation.

Remove Android hack around an old STL. Our Android builds use a newer STL now.
