sp_DatabaseRestore: Add param to enable service broker on restore

[lowlydba]

Is your feature request related to a problem? Please describe.
I'd like to be able to, via parameter, restore using sp_DatabaseRestore and include the functionality of ENABLE_BROKER (docs) so that existing service brokers in the restored database are enabled.

ENABLE_BROKER
Specifies that Service Broker message delivery is enabled at the end of the restore so that messages can be sent immediately. By default Service Broker message delivery is disabled during a restore. The database retains the existing Service Broker identifier.

Describe the solution you'd like
Something like @EnableBroker to achieve the above.

Describe alternatives you've considered
I can do it as a separate statement myself, but that could be said about most of this proc's functionality 🙃

Are you ready to build the code for the feature?
Sure, very easy implementation for this.

Makes sense! Go for it. Thanks!

Thanks for the PR! Looks good, makes sense, merging into the dev branch. I'm doing a July release a little early to get a couple of fixes into the Consultant Toolkit, and this will be in there.
