Add regression test for builtin attr macro values

[Ap4sh]

Adds a UI regression test for #145922

The test covers builtin attributes whose value is a macro call on a macro item, including the extra attributes mentioned in the issue thread. windows_subsystem still emits its normal malformed-attribute error; the other cases make sure they don't regress into the delayed ICE again

Fixes #145922

Tested:

• python3 x.py test tests/ui/attributes/builtin-attr-macro-value-issue-145922.rs --force-rerun -j 2
• python3 x.py test tidy -j 2
