cbf9cb27 - Break ambiguity for types conforming to both UEC and SVEC (#72800)

Break ambiguity for types conforming to both UEC and SVEC (#72800) * Break ambiguity for types conforming to both UEC and SVEC If an encoding container conforms to _both_ UEC and SVEC and does not itself implement support for [U]Int128, there is an ambiguity between the two default implementations. Add additional defaults defined on the intersection of the protocols to resolve this. * Update abi tests for new ambiguity breakers.
