- [x] Switch from a bash script to an xtask rust workspace member.
- Results in ~30s longer CI due to compilation of the xtask itself
- Enables Bevy contributors on any platform to run `cargo ci` to run linting -- if the default available Rust is the same version as on CI, then the command should give an identical result.
- [x] Use the xtask from official CI so there's only one place to update.
- [x] Bonus: Run clippy on the _entire_ workspace (existing CI setup was missing the `--workspace` flag
- [x] Clean up newly-exposed clippy errors
~#1388 builds on this to clean up newly discovered clippy errors -- I thought it might be nicer as a separate PR.~ Nope, merged it into this one so CI would pass.

* Rename reflect 'hash' method to 'reflect_hash' to avoid colliding with std:#️⃣:Hash::hash to resolve#943.
* Rename partial_eq to reflect_partial_eq to avoid collisions with implementations of PartialEq on primitives.
