zig fmt + some fixes for Zig 0.11 release

[dustyrockpyle]

I have a personal project I wanted to update to 0.11 that depends on protobuf-zig - thought I would send out a PR updating this library to Zig 0.11 in case it saves you some time.

I just ran zig fmt and then fixed up 3 or 4 alignment issues that were showing up in the tests on free. Some of the @as from zig fmt could probably be cleaned up.

All tests pass without issue on my machine

I had been seeing the same alignment on free problems and couldn't figure out how to fix them. Much appreciated! 👍

@dustyrockpyle would you mind leaving a comment explaining how you fixed the free alignment issue either here or in the 'files changed' tab? Its just to help me understand how you fixed the problem. Perhaps it was related to PtrAlignCast()? I just couldn't easily spot what changed looking through the changes.

Yeah probably should have done it this way to begin with, there's a better commit layout.

I might have missed some also - I only fixed what was showing up as errors in the tests. In my own code I believe I'm only reading protobufs from a buffer, so I never deinit them.
