[Editor] Merge duplicate entries in enum property inspector

[AThousandShips]

This helps with confusion over how selecting a key with a duplicate value won't be selected as only the first entry with a particular value will be selected.

See:

• Enumeration option cannot be selected in exported variable of type enum #96368

Disabling duplicated enumerators feels wrong to me because the underneath value is, in fact, usable. Having to use a different name defeats the purpose of giving the value an alternate name in the first place.

Maybe it's better to show duplicated enumerators as one entry. For example, for this enum

enum TestEnum2 { TEST = 1, TEST2 = 0, TEST3 = 1 }

show these two options:

• Test, Test3
• Test2

Can try that, bit more convoluted code, but unsure if it's not more confusing, the underlying issue here is that people get confused when clicking Test 3 it activates Test 1 and there's no clear indicator of why

But will test that, it'll be a bunch of additional code but should be easy

Pushed an alternative solution, however not sure how enum keys work with RTL languages in the interface so it might be weird with RTL languages being used, but someone knowledgeable in that can probably answer that

not sure how enum keys work with RTL languages in the interface

Localization of enum dropdowns in the inspector is currently disabled. We have not implemented string extraction for hint strings in editor codebase yet.

For user-defined texts like this, I think it's better to leave them untranslated.

Was more like how ", " would work if the individual hints are in an RTL language, but I don't know how the dropdown even behaves if a key is in RTL anyway so might not be a concern, i.e. if you do جَزِيرَة, بُحَيْرَة, it seem that it renders the same way as this does here (at least to my browser, not set to Arabic, I just took two Arabic words as an example I don't speak Arabic)

But I think that's probably a future problem to evaluate for the editor interface and not critical here
