Update unicode-width to 0.2.0

I updated the [`unicode-width`](https://github.com/unicode-rs/unicode-width) dependency to 0.2.0. See the changelog [here](https://github.com/unicode-rs/unicode-width?tab=readme-ov-file#changelog). None of the changes seem to affect rustc.

compiletest: Remove the one thing that was checking a directive's `original_line`

This special handling of `ignore-tidy*` was introduced during the migration to `//`@`` directives (rust-lang#120881), and has become unnecessary after the subsequent removal of the legacy directive check (rust-lang#131392).

Error on trying to use revisions in `run-make` tests

Currently, `run-make` tests do not support revisions.

compiletest: Move debugger setup code out of `lib.rs`

These functions contain a few hundred lines of code for dealing with debuggers (for `debuginfo` tests), and don't really belong in the crate root.

Moving them out to their own module makes `lib.rs` easier to follow.

switch unicode-data bitsets back to 'static'

Back in rust-lang#101401, these were changed to `const` to make some functions `const fn`. However, `@dtolnay` was [not happy](rust-lang#101400 (comment)) about this. Meanwhile, `const fn` can access immutable statics like these, so we can change this back.

Part of rust-lang#101400.

Special case error message for a `build-fail` test that failed check build

A `build-fail` test requires that a check build (roughly `--emit=metadata`, no codegen) succeeds but fails later. Previously, if its check build failed, the user will see the error message

```
error: test compilation failed although it shouldn't!
```

which is confusing. Because the test is `build-fail`, we want the test compilation to fail! This error message doesn't account for the difference between a check build and a complete build, so let's special case the error message for a `build-fail` test whose check build failed to instead say

```
error: `build-fail` test is required to pass check build, but check build failed
```

Fixes rust-lang#130894.
