Add compile-examples job to CI

[JulianGCalderon]

Adds a compile-examples job to the CI that compiles all examples.

This job can be set as non-required.

Questions:

• Should the job fail when an example fails to compile? Or just print it?
• Should we create a Github comment with the failing examples?

We test the examples under tests/cases.rs, that said maybe i missed some.

I think this is duplicating work, the cases.rs also checks the expected return value and output

[JulianGCalderon]

@edg-l I noticed that some examples where not working, so I created this PR to track them. Unlike rust tests, these workflows would test (only builds) all examples in the directory, helping us see which are outdated.

Failing Examples:
- examples/check_errors.con
- examples/enum.con
- examples/factorial.con
- examples/for_loop.con
- examples/union.con

That said, the new job takes much longer than the current jobs, so maybe its not worth to merge it.

I could add it as a script to the repository instead. It may come handy. What do you think?

[edg-l]

we should either remove those outdated ones or fix them, imho we already test them via rust code so this isn't as useful and looks like duplicating work a bit.
