feat: custom registries for targets in cargo-component new

This commit adds support for using custom registries with targets when
performing `cargo component new`. Users can specify a registry URI
like `oci://ghcr.io` along with a registry namespace prefix like
`bytecodealliance` and get easy access to packages (e.g. `docs:adder`)
that are provided therein.
