This CL adds a new `can-be-used-as-type` section in the dynamic
interface to expose the type of a class or extension type, without
making them callable or exposing their members.
Details:
* add the new section to the documentation
* add support in the TFA transformation to annotate kernel nodes
* add support to the validator to check for proper usage from dynamic modules
* add CFE, transformation, and end2end tests.
The CL ignores DDC and Dart2wasm at the moment and we intend to approve
any failures. It's possible that DDC works due to its modular nature.
BUG=b/488343137
TEST=cfe, annotator, and e2e tests
