fix(vats): buildDistributor call; refactor bootstrap.js

 - factor out registerNetworkProtocols
 - factor out makeChainBundler
   - add vatParameters arg
   - import types for vats
     - avoid casting result of buildZoe
   - turn bootMsg example comment into machine-checked type
 - default attMakerFor to non-bridge case rather than undefined
 - fix array arg to buildDistributor
 - factor out createLocalBundle
   - add vatPowers arg
 - refactor: unroll setupCommandDevice
 - feat: don't await vatAdminSvc
   I can't imagine any need for it to be local.
 - docs: prune refs to python provisioning service
   Is there anything left that's worth saying about "scenario #1"?
 - docs: declare type of makeFeeCollector
   move function comment into JSDoc
