Add RuntimeHints predicates generator

Browse Source 
The `RuntimeHints` API allows to describe hints for the reflection,
proxies and resources behavior at runtime. The need for a particular
behavior can be covered by several types of hints, at different levels.
This knowledge can be important in several cases:

* before contributing additional hints, infrastructure can check if an
  existing hint already covers the behavior
* this can be used in test suites and test infrastructure

This commit adds a new RuntimeHintsPredicates that generates `Predicate`
instances for testing `RuntimeHints` against a desired runtime behavior
for reflection, resources or proxies.

Closes gh-28555
