Warn if comptime item doesn't rely on non-comptime types

[asterite]

Problem

If a type, struct or enum is marked as comptime but doesn't refer to comptime-only types, a warning could be issued because the comptime keyword is not needed.

For example:

comptime type MyField = Field;
^^^^^^^^ unnecessary `comptime`: the type `MyField` doesn't refer to any comptime-only types

Happy Case

The compiler produces a warning in the above case.
