fix(ivy): remove debug utilities from ivy production builds (#30130)

Prior to this commit, we were pulling DebugNode and DebugElement
into production builds because BrowserModule automatically pulled
in NgProbe and thus getDebugNode. In Ivy, this is not necessary
because Ivy has its own set of debug utilities. We should use these
existing tools instead of NgProbe.

This commit adds an Ivy switch so we do not pull in NgProbe utilities
when running with Ivy. This saves us ~8KB in prod builds.
