[iOS/GN] Convert //ios/third_party/earl_grey to build with GN.

Fix the ios_framework_bundle template to create a new public config
so that anyone depending on the target will correctly link against
it. Change framework_bundle to use public_deps in order to make the
public config accessible.

Create //ios/third_party/earl_grey target.
