Add support for a new attribute `#[debugger_visualizer]` to support embedding debugger visualizers into a generated PDB.

Cleanup `DebuggerVisualizerFile` type and other minor cleanup of queries.

Merge the queries for debugger visualizers into a single query.

Revert move of `resolve_path` to `rustc_builtin_macros`. Update dependencies in Cargo.toml for `rustc_passes`.

Respond to PR comments. Load visualizer files into opaque bytes `Vec<u8>`. Debugger visualizers for dynamically linked crates should not be embedded in the current crate.

Update the unstable book with the new feature. Add the tracking issue for the debugger_visualizer feature.

Respond to PR comments and minor cleanups.

+# `debugger_visualizer`
+
+The tracking issue for this feature is: [#95939]
+
+[#95939]: https://github.com/rust-lang/rust/issues/95939
+
+------------------------
+
+The `debugger_visualizer` attribute can be used to instruct the compiler
+to embed a debugger visualizer file into the PDB/ELF generated by `rustc`.
+
+## Examples
+
+``` rust,ignore (partial-example)
+#![feature(debugger_visualizer)]
+#![debugger_visualizer(natvis_file = "foo.natvis")]
+struct Foo {
+
+}
+```
+
+## Limitations
+
+Currently, this feature only supports embedding Natvis files on `-windows-msvc`
+targets when using the MSVC linker via the `natvis_file` meta item.
