The enumEntriesIntrinsicMultipleEnums.kt test was supposed to check that
JVM backend generates 3 `$EntriesIntrinsicMappings` classes: for X, for
Y, and for Z. Mappings classes are generated for enums without
`entries`, i.e. Kotlin enums compiled without `EnumEntries` language
feature, and Java enums. The test incorrectly _enabled_ the language
feature for X though, and `$EntriesIntrinsicMappings` for X was
generated anyway because of KT-61208.
To keep the original intention of the test, I'm disabling the language
feature for X, so that it will be considered as enum without `entries`.
KT-61208 will be fixed in a separate commit (with separate tests).
The boxInline and bytecodeText tests changed their meaning when language
feature EnumEntries started to be enabled by default, so those changes
are a continuation to ebd43fc8c0. The behavior did not change after
enabling the feature, once again because of KT-61208.
Also, remove obsolete error suppressions which are no longer needed
after 64c8ce18a0.
Ensure that when .entries is accessed from an inline function body
or lambda argument, EntriesMapping are properly generated and used
without excessive mappings and duplicated fields
