fix(metadata): Stabilize id format as PackageIDSpec

### What does this PR try to resolve?

For tools integrating with cargo, `cargo metadata` is the primary interface.  Limitations include:
-  There isn't an unambiguous way to map a package entry from `cargo metadata`  to a parameter to pass to other `cargo` commands.  An `id` field exists but it is documented as an opaque string, useful only for comparisons with other `id`s within the document.
- There isn't an unambiguous way of taking user parameters (`--package`) and mapping them to `cargo metadata` entries.  `cargo pkgid` could help but it returns a `PackageIdSpec` which doesn't exist within the `cargo metadata` output.

This attempts to solve these problems by switching the `id` field from `PackageId` to `PackageIdSpec` which is a [publicly documented format](https://doc.rust-lang.org/cargo/reference/pkgid-spec.html), can be generated by `cargo pkgid`, and is accepted by most commands via the `--package` flag.

As the `"id"` field is documented as opaque, this technically isn't a breaking change though people could be parsing it.

For `cargo_metadata` they do [use a new type that documents it as opaque but publicly expose the inner `String`](https://docs.rs/cargo_metadata/latest/cargo_metadata/struct.PackageId.html).  The `String` wasn't publicly exposed due to a request by users but instead their `PackageId` type replaced using `String`s in the API in oli-obk/cargo_metadata#59 with no indication given as to why the `String` was still exposed.  However, you'll note that before that PR, they had `WorkspaceMember` that parsed `PackageId`.  This was introduced in oli-obk/cargo_metadata#26 without a motivation given.

**Note that `PackageIdSpec` has multiple representation that might uniquely identify a package and we can return any one of them.**

Fixes #7267

### How should we test and review this PR?
