build: simplify bazel usage (#336)

This change includes @bazel/bazelisk as a dependency and runs all build/test execution through NPM removing dependency on a local Bazel installation.

Also changes the following:

- pre/post build hooks
- uses rimraf for cross platform compatibility
- removes bazel cache as it is not necessary
