Unity Testsuite

[jdetter]

Description of Changes

Describe what has been changed, any new features or bug fixes

• This PR introduces a testsuite which runs in Unity. I have started with the SpacetimeDBCircleGame but I think we should add more small example games in the future. Right now it just spawns in a circle, eats some food and verifies the decay logic is working correctly. I've also written some reconnection tests but they don't work because reconnections are currently broken. There are also one-off tests but those don't work either because they also require reconnections to be working.

Update: reconnections have been fixed via https://github.com/clockworklabs/com.clockworklabs.spacetimedbsdk/pull/168 . In that PR I have enabled all tests!

I've used the built-in unity testsuite framework to achieve this, along with the UnityCI tool from GameCI. The documentation for this docker container can be found here: https://game.ci/docs/github/getting-started/

Rendered README for our testsuite which includes local testing instructions: https://github.com/clockworklabs/com.clockworklabs.spacetimedbsdk/blob/jdetter/unity-testsuite/unity-tests~/README.md

Ingvar suggested we add a check which verifies that the client bindings on the branch being tested are up-to-date, I agree with this and I've added the check.

@jdetter I am going to approve this, however, I am also going to schedule a meeting with @RReverser @SteveBoytsun @lcodes @Centril with the purpose of having you explain in person how it works, so that we can hand it off to others with them being able to understand the tricky problems of setting this up.

Should merge after this: https://github.com/clockworklabs/com.clockworklabs.spacetimedbsdk/pull/177

[Centril]

Rebased this atop of a rebased jdetter/unity-testsuite-import which was rebased atop of staging (https://github.com/clockworklabs/com.clockworklabs.spacetimedbsdk/pull/177#issuecomment-2446883581) and changed back the merge-into target branch to clarify the diff for review purposes.

Also changed the test-against stdb commit to 0935b7346b825b8cbb9f36d9ed256136b73b5f0b, currently the HEAD of master.
