Enum doesn't print correctly

[aconsroe-hpe]

Summary of Problem

Enum values with the same given value don't print correctly.

Steps to Reproduce

Source Code:

enum foo1 {bar = 0};
writeln(foo1.bar);

enum foo2 {Bar = 0};
writeln(foo2.Bar);

enum foo3 {bar = 0, Bar = 0};
writeln(foo3.bar);
writeln(foo3.Bar);

Compile command: chpl multipleenums.chpl

bar
Bar
bar

I expected the last line to be Bar

I believe this is already fixed in #18708 which has yet to be merged. That's fallen out of my active working set because I didn't want to merge it without a fix for the performance hit that it results in (and definitely didn't want to merge it before 1.25.1).
