Adapt to rust-lang/rust#136466:

Start removing `rustc_middle::hir::map::Map`

Following commit f86f7ad from pull request #136466
in the Rust project
(https://github.com/rust-lang/rust),
some methods in `Map` were moved to `TyCtxt`.
This update reimplements `rustc-drive-example.rs`,
`rustc-driver-interacting-with-the-ast.rs`,
and `rustc-interface-example.rs` using the new
versions of these methods, ensuring compatibility
with the nightly-2025-03-08 toolchain.
