google: add some metadata to GCE tokens to identify the token's source

This is required for the direct path feature, which only works with this
token source. It's not currently possible to determine the token source
type from the return value of FindDefaultCredentials.

Another option is to add another field to the Credentials struct, which
we could still do later, but direct path is currently pretty experimental
and whitelisted/opt-in, so I don't want to add to the public API surface
unnecessarily.
