Private feature switches:

• CanCompileToIL and
• CanCreateArbitraryDelegates

are not needed anymore as they got replaced by IsDynamicCodeSupported

Additionally:

• CanEmitObjectArrayDelegate

should be set in RuntimeHostConfigurationOption by build integration targets, instead of explicitly passing the switch to ILC, so other tools (ILLink) can also understand the desired trimming configuration.
