Series [1/9] classes/cargo_common: move PKG_CONFIG_ALLOW_CROSS export to oe_cargo_fix_env | expand

Move the dependencies from cargo to cargo_common: if cargo is being used
in any way then you need to depend on cargo-native.

Inherit rust instead of rust-common or rust-target-config: rust inherits
rust-common that inherits rust-target-config, and rust.bbclass simply
adds the dependency on rust-native. This means we can drop the explicit
rust dependencies to avoid duplication.
