cleanup: Remove test deps on //@npm//@angular/compiler. (#6074)

Remove seemingly unnecessary deps from test libraries on
`//@npm//@angular/compiler`.

Why these subset of tests have this dependency is unknown to me - none
of the corresponding test files actually `import @angular/compiler;`.
Looking at the generated bundles for these tests, the output appears
only partially compiled (ie the bundled output is more akin to
`//tensorboard:dev` than `//tensorboard`), but if the angular compiler
is actually included by the test runtime then it is done somewhere deep
in the test framework. Not sure if it is Karma or spec_bundle() or
elsewhere.

To test:
* Run the tests. They pass.
* Check I got all the instances in tests:
  ```
  $ grep -r "angular/compiler" *
