[native_toolchain_c] Add a default Logger

[dcharkes]

Bug:

• For all generators and builders: Logger argument behavior #2645

The log level is defaulted to INFO. Looking at various places in the code base that's a desired level. However, we could consider also swapping it to WARNING.

Side note: Maybe we'll have less logging messages once we support a dedicated progress update:

• [hooks_runner] Progress updates for dartdev #2439

Add some information to the doc comment about default logging behavior and how to change it?

Should this be changed too?

(Asking since I’m currently implementing this interface and was wondering haha)

[dcharkes]

Yes, I think we should. (It's a pity we can't provide a default on the interface itself, so every implementer needs to provide the same sensible default.) I have on my list to make that change and update package:native_toolchain_c.
