Switch from @silent to @nowarn. (#9498) 
* Switch from `@silent` to `@nowarn`.

This annotation is native to Scala 2.12.13+ and 2.13.2+. It replaces
most usages of `@silent`.

I had to get creative about a couple of use cases that didn't work.
Specifically:

  1.  Suppressing deprecation warnings works, but Scala 2.12 erroneously
      complains that the `@nowarn` is unnecessary.  I had to suppress
      this warning too with `-Ywarn-unused:-nowarn`.
  2.  I can't seem to suppress the warning, "The outer reference in this
      type test cannot be checked at run time." Instead, I have
      refactored the code to remove the warning.

We still need to use the silencer plugin to suppress some warnings about
unused imports (because of compatibility between Scala 2.12 and 2.13),
but this means we no longer need the library, and therefore it is not a
transitive dependency that downstream consumers need to worry about.

CHANGELOG_BEGIN
CHANGELOG_END

* Add some comments around `@nowarn` support.

* language-support/scala: Fix a warning suppression.

* Revert to the default warnings.

Compatibility was complaining.
