CORE-15267 Make MemberInfo serializable

[YashNabar]

Makes MemberInfo serializable by registering custom serializers for MemberContext and MGMContext. The corresponding corda-api change marks these interfaces as @CordaSerializable - corda/corda-api#1341

This change was tested manually using a modified version of the combined worker smoke tests, by including MemberInfo in one of the flow states used by the tests. [build]
It was also manually confirmed that this change does not break ABI compatibility, by running a modified version of the end-to-end flow tests against a combined worker compiled with the newer corda-api version.

Is it possible to add some unit tests for these serializers? You might need to declare a test dependency on the AMQP serialization library to do so. There may be some issues around sandboxing that make this difficult/impossible, but worth investigating.

Discussed offline, end-to-end tests and any possible unit tests to be added in a follow-up PR (cc @dimosr @JamesHR3)
