Rollup merge of #152570 - Ozzy1423:attr-parse, r=JonathanBrouwer

Port #[rustc_test_marker] to the attribute parser

Tracking issue: rust-lang/rust#131229

Targets:
Const is for normal tests (const test::TestDescAndFn is inserted before the test fn)
Const/Static/Fn is for custom_test_framework's #[test_case] e.g. tests/ui/custom_test_frameworks/full.rs

r? @JonathanBrouwer

Again I left the use-sites as is since they are early uses.
