Extract all logic in modifiedRunLoop to small injections

[altrisi]

Reviewing wanted! I'm not good at all with mixins, and although this has taken me a while and I've tried to check and the output is similar, it may not be the same! And this is quite a core part of Carpet (and vanilla!) that I'd prefer to not have messed up.

This PR gets rid of modifiedRunLoop and instead separates it into smaller mixins to the specific places where Carpet was changing its behaviour. This has the following benefits:

• Removes the possibility for it to get out of sync with vanilla (it actually already was, though only vs a JFR profiling event) and having to check for that
• Improves mod compatibility with mods that change other stuff in the run loop. Currently any mod that injected any logic there would just be silently skipped, IMO the worst of compatibility issues
• Removes it from logs in a few places where we wrapped vanilla logic reducing reports and confusion with people thinking the crashes were caused by Carpet
• Removes the workaround of TimeProfiler being private that meant we had to copy all the logic that used it with our own type

As a compromise, the local variable msThisTick is now global, but shouldn't be an issue given that should always accessed by the same thread and in the same section.

Missing (only ideally, likely not really needed for it to just work):

• Replacing l = Util.getMillis() - this.nextTickTime; with our l in the preTick (currently lost)

Resolves #1747.

It got extracted further it seems!
