Fix missing syntax highlighting for &raw const / &raw mut in all files.

[Shourya742]

closes: #19357

[Shourya742]

@Veykril, with our current test fixture infrastructure, we can't write tests for non-crate files. The test expects the error: "missing default crate root, specify a main.rs or lib.rs."

If I want to test something like this, it won't work:

    check_highlighting(
        r#"
//- /foo.rs
fn main() {
    let x = &raw mut 5;
}
"#,
        expect_file!["./test_data/highlight_issue_19357.html"],
        false,
    );

Should we make changes in the same PR to support this test?

I think

check_highlighting(
    r#"
//- /foo.rs
fn main() {
    let x = &raw mut 5;
}
//- /main.rs
"#,

might work?
