[iOS/GN] Convert //ios/third_party/ochamcrest to build a framework.

Add support for copying public headers to the ios_framework_bundle
template and use this to implement the //ios/third_party/ochamcrest
target.

Add a set_defaults for ios_framework_bundle and mac_framework_bundle
to build/config/BUILDCONFIG.gn so that overriding "configs" works as
expected.
