3cf280c1 - Emit nested unused enum types with -fno-eliminate-unused-debug-types (#137818)

Emit nested unused enum types with -fno-eliminate-unused-debug-types (#137818) Unused types are retained in the debug info when -fno-eliminate-unused-debug-types is specified. However, unused nested enums were not being emitted even with this option. This patch fixes the missing emission of unused nested enums with -fno-eliminate-unused-debug-types
