feat(coderd): add provisioner build version and api_version on serve (#11369)

* assert provisioner daemon version and api_version in unit tests
* add build info in HTTP header, extract codersdk.BuildVersionHeader
* add api_version to codersdk.ProvisionerDaemon
* testutil.MustString -> testutil.MustRandString
