feat(coderd): add matched provisioner daemons information to more places (#15688)

- Refactors `checkProvisioners` into `db2sdk.MatchedProvisioners`
- Adds a separate RBAC subject just for reading provisioner daemons
- Adds matched provisioners information to additional endpoints relating to
  workspace builds and templates
-Updates existing unit tests for above endpoints
-Adds API endpoint for matched provisioners of template dry-run job
-Updates CLI to show warning when creating/starting/stopping/deleting
 workspaces for which no provisoners are available
