Deprecate RuntimeHintsAgent Java agent

This Java agent has been designed to instrument specific JDK calls for
reflective introspection and invocations. This is useful for testing
runtime hints in integration tests.

As of GraalVM 23, there is a new VM option that does this in a much more
efficient and precise fashion. Developers can use the
`-XX:MissingRegistrationReportingMode` with the "Warn" or "Exit" value.
The option will look for reachability metadata and emit logs in "Warn"
mode or immediately exit the application with in "Exit" mode.

This commit deprecates the `RuntimeHintsAgent` in favor of this new,
more reliable option.

See gh-33847
