lang/rust: Install Cargo + use bundled crates

This port now provides Cargo. This is the recommended now because Cargo
won't be provided separately in the future.

To build Cargo, we set `extended = true` in `config.toml`. As a side
effect, this flag also installs Rust source code. The port has a new
`SOURCES` option (disabled by default) to keep those sources.

As a consequence of this, `devel/cargo` is removed. Several ports
and Makefiles in Mk were updated to depend on `lang/rust` instead of
`devel/cargo`.

The other big change in this patch is the use of the bundled crates,
instead of relying on Cargo's registry (which was part of the distfiles,
