build: migrate determining if Ivy is enabled in typescript genrule files to use angular_ivy_enabled (#33983)

Use angular_ivy_enabled to determine if Ivy is being used for the ivy_test_selector.ts symbols.
Additionally, remove the reflect_metadata genrules as we not longer have a "jit" compile option
so all possible invocations result in the same generated file.  Instead we can just commit this
file.
