Set the max buffersize for jsoniter

This is a first take on #2458

Let me know if there's something missing, or if I should try another way to do this.

Could we also add a test case in TapirAdapterSpec that would fail using the pre-PR code? That way we can ensure that the implicits are all properly used across all adapters.

I added a test case, but it currently also fails on this branch -- we're getting 413 Request Entity Too Large from PlayAdapterSpec and QuickAdapterSpec. I'm working on figuring out how to make these two servers accept larger payloads. I did verify that it reproduces the error on series/2.x.

@ghostdogpr want to take a new look? There's a test case that fails on main and works on the branch now. I tried to avoid using application.conf for the PlayAdapterSpec, but I was unable to make the settings stick by passing them as properties. 🤔

Thanks!
