This adds the static assert for packing length that we had in #[note] to #[event] as well, and also adds links to the docsite, where in the future we may have information as to how to proceed (e.g. what to do with too-long events etc).

Add a static_assert to the #[event] macro that validates event serialized
length does not exceed MAX_EVENT_SERIALIZED_LEN, mirroring the existing
check in the #[note] macro. Add error code URLs to both the note and
event static_assert messages linking to docs.aztec.network/errors/{4,5},
with corresponding netlify redirects. Add an invalid_event compile
failure test.

@nventuro The code in this PR was broken so I fixed it. The fixes I needed to do are in the last 3 commits.
