[FR]: Use hermetic Java toolchain to execute npm lifecycle hooks

### What is the current behavior?

Some NPM packages execute Java or use Java paths ([example package](https://github.com/joeferner/node-java)) in their postinstall hooks. Those paths currently point to the system JDK.

### Describe the feature

We'd like to be able to use the Bazel Java toolchain when running lifecycle hooks instead.

Ideally this is a general solution for passing in hermetic toolchains for actions run by `npm_import`

Start at the npm_import entry point and trace how lifecycle hooks currently receive Java paths from the system JDK. Investigate how a Bazel Java toolchain could be passed to those actions, then define completion as a general hermetic toolchain mechanism that works for npm lifecycle hooks and the example Java-using package.
