feat: print target and package names formatted as file hyperlinks (rust-lang#15405)

Resolves rust-lang#15401

Here is an example of the feature in
[kitty](https://sw.kovidgoyal.net/kitty/) `0.40.1` with the following
config set in `~/.config/kitty/kitty.conf`

```conf
underline_hyperlinks always
show_hyperlink_targets yes
allow_hyperlinks yes
# ...
```

![cargo-target-file-hyperlik-kitty-showcase](https://github.com/user-attachments/assets/04155d5a-a254-4e80-a35e-a02cc4671ae4)

Tested on `uname -a`:
```
Linux nixos 6.14.0 #1-NixOS SMP PREEMPT_DYNAMIC Mon Mar 24 14:02:41 UTC 2025 x86_64 GNU/Linux
```
Terminals tested with:
- [x] [kitty](https://sw.kovidgoyal.net/kitty/) `0.40.1`
- [x] [ghostty](https://ghostty.org/) `1.1.4-6f1b22a-nix`

The following `cargo` invocations will have their output be modified by
this change:
```shell
cargo run # If multiple binaries are defined in the manifest and [package.default-bin] is not defined
cargo run --bin
cargo run --example
cargo run --package
cargo build --bin
cargo build --example
cargo build --package
cargo test --test
cargo test --bench
```

In addition I have done a slight refactor to have the printed indent of
targets and packages be the same by using a shared constant named `const
ITEM_INDENT: &str = " ";`

This is my first PR to the cargo codebase, so I am not familiar with
what is expected in terms of test for a feature such as this.
