Upgrade npm bazel rules to latest

Later than v2, rollup_bundle needs additional configuration to find
workspace files. It also no longer minifies, so needed to add an
additional post-bundle step to maintain api.

We had to rename the `Object` class to `ObjectGenerated` in the
flatbuffers TypeScript generator. This lets us avoid name clashes with
the builtin `Object` class.
