Add dependency on http-auth-aws-crt from auth-crt. (#4504)

Customers currently depend on auth-crt to get Sigv4a support. In the future, customers should depend on http-auth-aws-crt for Sigv4a support. In order to ensure existing customers still work after SRA, we want users who depend on auth-crt today to automatically depend on http-auth-aws-crt.
