feat: macro-generated serialization tests

[huitseeker]

This PR against #2071 implements a serde_test macro that can generate round-trip serialization tests pegged on an implementation of proptest::prelude::Arbitrary. This macro:

• supports generic arguments passed as attributes,
• uses bincode serde_json as the test serializer (I expect this will be replaced by feat: implement new binary format, BITE #2130)

=> no more boilerplate tests! (and future tests are easier to define)

Note

Tests failing here are signal for #2071 (unless I messed up something in my Arbitrary impls).

TODO (after merging this PR)

• make sure the import of the miden-serde-test-macros crate is sparse and follows best practices re: features. (I've been fast & loose),
• check CI / Makefile to ensure those feature-gated tests are run (i.e. the failure in the present PR's CI is still observed after tweaking features as per the above),
• have a better implementation of Arbitrary for LibraryExports (where the last field isn't always None), add one in missing places, e.g. KernelLibrary,
• fix failing tests (see feat: implement custom sections in package format, prototype new serialization format #2071 review)

Note that our use of serde requires a self-describing format to work properly, and bincode is not. This was one of the main motivations behind the miden-bite design.

I'd suggest we either pick a binary format this is self-describing for these tests, or punt on merging this until miden-bite (or whatever format we land on there) is merged.
