Optimize binstalk-{manifest, types} (#610)

* Add new dep maybe-owned v0.3.4 to binstalk-types with features serde
* Re-export maybe_owned in binstalk-types
* Optimize `CrateSource::url`: Use `MaybeOwned<'static, Url>`
   to avoid cloning in `CrateSource::cratesio_registry`
* Optimize `Source`: Use `MaybeOwned<'static, Url>`
   to avoid cloning in `Source::cratesio_registry` and
   `impl From<&CrateSource> for Source`.
* Optimize `Source`: Add lifetime `<'a>` to avoid cloning
   in `impl<'a> From<&'a CrateSource> for Source<'a>`
* Optimize `CratesToml::append_to_path`: Avoid cloning
   caused by `CrateVersionSource::from` by manually `format!` name, version
   and source into string.
* Add new dep beef v0.5.2 to binstalk-manifests with features impl_serde
* Optimize `CratesToml::append_to_path`: Eliminate `metadata.bins.clone()` by using `Cow`
* Replace dep toml_edit with toml v0.5.10 in binstalk-manifests
   to speed up compilation and reduce bloat.
   
   Previously we switch to toml_edit because it is unmaintained, but now
   with it moved into toml-rs/toml as a workspace, it is now under active
   maintenance again, thus we switch back to it.
