Add Lottie to ios/third_party.

Pull the latest Lottie objc branch via DEPS to ios/third_party.
Use the GN file in a similar structure as material_component_ios.
Add `ios_chrome_links_with_lottie_framework`, will be switched to true
after ios_internal is updated with the flag.
Use Lottie.h in code for demo purpose - this part will be removed when
landing the CL.
