Fix Float/Double meta data options not showing up.

[BenVlodgi]

Unreal Engine Version: 5.3

I didn't test in other engine versions.

Bug

Metadata keys which explicitly supported Float/Double/Real types do not show up. (i.e. SliderExponent, Delta, Multiple, NoSpinbox)

Cause

In UE 5.3 Floats and Doubles are actually Reals, with the subtype of Float/Double. These keys were failing to be supported because Key.DoesSupportProperty(Property) would return false. Because it requires the type and subtype to match.

Fix

• The config was updated to initialize
  • floats as { UEdGraphSchema_K2::PC_Real, UEdGraphSchema_K2::PC_Float }
  • doubles { UEdGraphSchema_K2::PC_Real, UEdGraphSchema_K2::PC_Double }
  • With no extra { UEdGraphSchema_K2::PC_Real }
• The constructor for the struct was updated to FixUp() the values if they are being initialized incorrectly by code.
• The config was updated to also call FixUp() on PostInitProperties() so that configurations which were saved with previous versions would be fixed also.

Tested

• Picking double type in the plugin settings menu already correctly set the type & subtype.
• I verified: The new initializing of floats/doubles in the config fixes the issue.
• I verified: Loading an old broken config gets fixed.
• I verified: Adding the type's in code the old way gets automatically fixed.
  • Adding a naked float/double gets fixed.
  • Adding a naked real gets set to be a double.
  • Duplicates are automatically removed (because it is a TSet).
