rust.workspace() is the entry point for global feature resolution. It loads a Cargo.toml file and ensures that all dependencies will be built with the correct set of features. Fixes: mesonbuild#13404
Add features property to cargo.Interpreter to make default features configurable; customization of which features are enabled by default is triggered by rust.workspace(). Fixes: mesonbuild#14290

This introduces a skeletal implementation of #14639, which however is already relatable to what is implemented by the cmake module. In particular, workspace().subproject() works, and allows retrieving the overridden dependency as well as the Cargo features of the crate.
