rustdoc: Show attributes on all item types
Currently attributes are only shown for structs, unions and enums but
they should be shown for all items. For example it is useful to know if a
function is `#[no_mangle]`.

Display correct filename with --test option
Fixes#39592.
With the current files:
```rust
pub mod foo;
/// This is a Foo;
///
/// ```
/// println!("baaaaaar");
/// ```
pub struct Foo;
/// This is a Bar;
///
/// ```
/// println!("fooooo");
/// ```
pub struct Bar;
```
```rust
// note the whitespaces
/// ```
/// println!("foo");
/// ```
pub fn foo() {}
```
It displays:
```

* Don't disambiguate if there are multiple impls for the same type.
* Disambiguate for impls of &Foo and &mut Foo.
* Don't try to disambiguate generic types.
rustdoc: mark FFI functions with unsafety icon
Currently, in the list of functions, unsafe functions are marked with a superscript ⚠, but unsafe FFI functions are not. This patch treats unsafe FFI functions like other unsafe functions in this regard.
Refactor the parser to consume token trees
This is groundwork for efficiently parsing attribute proc macro invocations, bang macro invocations, and `TokenStream`-based attributes and fragment matchers.
This improves parsing performance by 8-15% and expansion performance by 0-5% on a sampling of the compiler's crates.

Fix rustdoc highlighting of `&` and `*`
Whitespace tokens were included, so the span check used with `&` was incorrect, and it was never highlighted as kw-2 (RefKeyword).
The `*` in `*foo` and `*const T` should also be highlighted kw-2, so I added them. Note that this *will* cause mishighlighting of code like `1*2`, but that should have been written `1 * 2`. Same deal with `1&2`.
rustdoc: properly calculate line length for where clauses
Apparently, while I was cleaning up #37190, I regressed the formatting for long where clauses, where it wouldn't take the "prefix" length into account when deciding whether to break the line up. This patch fixes that.
