Group Message Kind

[nplasterer]

Part of xmtp/libxmtp#522

Adds the message kind to returned message. Then filters for them in the SDK so that GroupMembershipChange Codecs will only get through the messages list if it also has a Membership_Change kind.

Updates + tests all look good. One thing I noticed is that for me this PR branch shows LibXMTP Version empty in the logs for some reason. I'm not sure if maybe bindings were generated in a different way that could cause that. I double tested the version shows up for fine me on main, but not this branch for some reason.

LibXMTP Version: 
Branch: 
Date:

Separate from the version not showing up in logs for some reason - it still feels to me that the libxmtp version should be stored somewhere in the project so that we don't have to build and check logs to see what commit hash of libxmtp android is using. Maybe until we automate that, just adding the libxmtp commit hash to description of PRs that update the bindings would be a good failsafe. wdyt?

gen_kotlin.sh creates a libxmtp-version.txt next to the xmtpv3.kt in bindings_ffi/src/uniffi/xmtpv3, if it's helpful maybe we can modify any scripts to copy it over at the same time as xmtpv3.kt and check that file into this repo too?

Also, sorry that the libxmtp version sometimes doesn't show up in code - the build.rs in bindings_ffi doesn't always trigger. It can be fixed by manually running make libxmtp-version and rebuilding the bindings.

It might be nice to ensure that make libxmtp-version triggers in cross_build.sh instead of build.rs and gen_kotlin.sh, but the github action would need to be updated too. Hoping I can hand this off to someone? Can explain more if needed

I copied over the libxmtp txt file. Next time I'm in libxmtp I can take a look at updating the script. 👀
