Rollup merge of #78658 - casey:x, r=Mark-Simulacrum

Add a tool to run `x.py` from any subdirectory

This adds a binary called `x` in `src/tools/x`. All it does is check the current directory and its ancestors for a file called `x.py`, and if it finds one, runs it.

By installing x, you can easily run `x.py` from any subdirectory, and only need to type `x`.

It can be installed with `cargo install --path src/tools/x`

This is a copy of a [binary I've been using myself when working on rust](https://github.com/casey/bootstrap), currently published to crates.io as `bootstrap`.

It could be changed to avoid indirecting through `x.py`, and instead call the bootstrap module directly. However, this seemed like the simplest thing possible, and won't break if the details of how the bootstrap module is invoked change.
