[PATCH v4 06/10] qapi/block-core: use JobType for BlockJobInfo's type

[Fiona Ebner <f.ebner@proxmox.com>]

In preparation to turn BlockJobInfo into a union with @type as the
discriminator. That requires it to be an enum. Even without that
requirement, it's nicer to have an enum instead of a str here.

No functional change is intended.

    * Mention that it's nicer to have an enum regardless in commit
