Use revisions to test `min_const_generics`

[lcnr]

cc #74878

#74877 implemented feature(min_const_generics) which is split off from feature(const_generics).

As these two features have some meaningful differences it is desirable to run try and run all const generics tests with both features.

This can be done usingrevisions. Some tests were already updated in #74877:

rust/src/test/ui/const-generics/issues/issue-56445.rs

Lines 1 to 13 in f9c2177

	// Regression test for https://github.com/rust-lang/rust/issues/56445#issuecomment-518402995.
	// revisions: full min
	#![cfg_attr(full, feature(const_generics))] //[full]~WARN the feature `const_generics` is incomplete
	#![cfg_attr(min, feature(min_const_generics))]
	#![crate_type = "lib"]
	use std::marker::PhantomData;
	struct Bug<'a, const S: &'a str>(PhantomData<&'a ()>);
	//~^ ERROR: use of non-static lifetime `'a` in const generic
	//[min]~| ERROR: using `&'static str` as const
	impl Bug<'_, ""> {}
