Move compile fail tests (#13196) # Objective - Follow-up of #13184 :) - We use `ui_test` to test compiler errors for our custom macros. - There are four crates related to compile fail tests - `bevy_ecs_compile_fail_tests`, `bevy_macros_compile_fail_tests`, and `bevy_reflect_compile_fail_tests`, which actually test the macros. - [`bevy_compile_test_utils`](https://github.com/bevyengine/bevy/tree/64c1c65783938facc59d9b36cbaa6deba435d84e/crates/bevy_compile_test_utils), which provides helpers and common patterns for these tests. - All of these crates reside within the `crates` directory. - This can be confusing, especially for newcomers. All of the other folders in `crates` are actual published libraries, except for these 4. ## Solution - Move all compile fail tests to a `compile_fail` folder under their corresponding crate. - E.g. `crates/bevy_ecs_compile_fail_tests` would be moved to `crates/bevy_ecs/compile_fail`. - Move `bevy_compile_test_utils` to `tools/compile_fail_utils`. There are a few benefits to this approach: 1. An internal testing detail is less intrusive (and confusing) for those who just want to browse the public Bevy interface. 2. Follows a pre-existing approach of organizing related crates inside a larger crate's folder. - See `bevy_gizmos/macros` for an example. 4. Makes consistent the terms `compile_test`, `compile_fail`, and `compile_fail_test` in code. It's all just `compile_fail` now, because we are specifically testing the error messages on compiler failures. - To be clear it can still be referred to by these terms in comments and speech, just the names of the crates and the CI command are now consistent. ## Testing Run the compile fail CI command: ```shell cargo run -p ci -- compile-fail ``` If it still passes, then my refactor was successful. 2024-05-03 13:35:21 +00:00			`fn main() -> compile_fail_utils::ui_test::Result<()> {`
