feat(swingset): defaultManagerType option in makeSwingsetController

... and to buildVatController Usage: WORKER_TYPE=xs-worker yarn test or: XSNAP_DEBUG=1 WORKER_TYPE=xs-worker yarn test or: XSNAP_DEBUG=1 WORKER_TYPE=xs-worker yarn test --watch ref #2260 - fix: comms vat must be local to use setUp - chore(swingset): log fallback-to-local workerType - chore: refine xs-worker diagnostics - chore(xs-worker): include vatID in log messages - fix(xs-worker): catch exceptions from exception handler - chore(swingset): use ambient process.env unless caller overrides - fix(swingset): proplems in types.js shown by @ts-check
