Logger Fixes for Windows

[MichealReed]

The way we were printing from LOG caused a crash when embedded on windows. This updates the logger to be more typesafe and generally compatible across platforms.

I removed exit(1) from the check function. We should never automatically exit the program as a library, this can prevent proper logging if there is indeed a crash.

Also introduces a NO_LOG definition that we should add throughout.

Also adds log level 0 for silent output.

+1 to the exit policy. Error handling in general will needs some consideration.

There's quite a few places where the return type should conceptionally return optional types (Error or Value), but that does add some complexity to the API and optional types aren't as clean / idiomatic in C++ as they are in rust or zig. OTOH i don't like the idea of throwing exceptions either, but we'll have to bite the bullet one way or another and probably commit to something in the near future.
