Added native Bazel build to GUI2. Reduced a lot of the unused Angular CLI structures

Reviewers should look at the changes in WORKSPACE, BUILD, BUILD.bazel, README.md files
This is only possible now as rules_nodejs went to 1.0.0 on December 20
gui2 has now been made the entry point (rather than gui2-fw-lib)
No tests or linting are functional yet for Typescript
Each NgModule now has its own BUILD.bazel file with ng_module
gui2-fw-lib is all one module and has been refactored to simplify the directory structure
gui2-topo-lib is also all one module - its directory structure has had 3 layers removed
The big bash script in web/gui2/BUILD has been removed - all is done through ng_module rules
in web/gui2/src/main/webapp/BUILD.bazel and web/gui2/src/main/webapp/app/BUILD.bazel
