Feature: Micronaut Support

This changeset adds basic initial support for Micronaut, with new
rule macros which inject dependencies, and support for a basic
testbed which works.

Changes so far:
- [x] Add Micronaut dependencies
- [x] Add rule macros for Micronaut libs/apps/etc.
- [x] Add a little testbed which executes controllers
  - [x] Add tests for Kotlin and Java
  - [x] Invoke Micronaut from a browser test
    - [x] From Java
    - [x] From Kotlin (this required a patch at
          bazelbuild/rules_webtesting#409)
- [x] Ability to opt-out of Micronaut dependencies
