Enable `--progress` flag by default on a TTY

[straight-shoota]

We should enable --progress by default for crystal build etc. when the output a TTY. Printing progress information shows that the compiler is at work. Builds can take a while sometimes and users might assume it's stuck or something. Seeing something happen also makes it feel faster.

While doing that we should offer a flag to disable progress output (--no-progress).

This was first mentioned in https://github.com/crystal-lang/crystal/issues/16254#issuecomment-3434222295

While I fully agree with this, if a --single-module build still takes many minutes to run, is there any extra progress indication we could show?

Yeah, for single module and release it's still not gonna move, unless we put an ASCII animated loader as to say "not dead, still alive, doing my thing".

I'd suggest to start with simply enabling --progress by default. And further enhancements as a next step.
