Upgrade go-msgpack to v2 2.1.1 (#23750)

And set the `time.Time` option to use the go-msgpack-1.1.5-compatible
encoding in all the places, since that is the (now previous) version in
`go.mod`.

v2 2.1.1 was specifically designed to honor backwards compatibility
with 1.1.5 and 0.5.5, and to clean up the code base to be more
maintainable. There may performance lost with the 1.1.5 to 2.1.1
migration since the fastpath code was removed, but the increased safety
is probably worth it. See
[the release notes for go-msgkack 2.1.0](https://github.com/hashicorp/go-msgpack/releases/tag/v2.1.0)
for more details.

I tested this by running this code, and booting up a cluster with a node
also running Vault 1.15.0 (before the upgrade). Before I made the
changes to set the right `time.Time` option, the previous-version node
would throw a bunch of time-decoding errors. After fixing the option,
the node came up smoothly, even after changing leadership between them.

This relies on
- hashicorp/raft-boltdb#38
- hashicorp/raft#577

I did a simple pair of benchmarks (one with a final sync, one without)
and ran them before and after on both my Mac (M2 Max) laptop and my
Linux (AMD Threadripper 3970X) desktop.

tl;dr There was no performance difference for this benchmark.
