JvmDefault: remove most tests on @JvmDefault

The tests are removed because JvmDefault is going to be deprecated with
error in KT-54746 and removed later in KT-57696.

Many of the removed tests already had existing counterparts with the new
modes `all` and `all-compatibility`. In this change, I've added such
tests where they were missing, and removed tests which were testing
behavior specific to the JvmDefault annotation, such as some
diagnostics.
