[3.0] Apply MaybeBool transformation to fields/properties (#2574)

* Update docs for TransformProperties to prepare for my boolean transformation change

* Adjust doc wording

* Cleanup and add missing file header

* Change TransformFunctions.Configuration.BoolTypes to be non-nullable for simplicity

The performance difference is negligible.

* Add MaybeBool transformation to fields and properties

* Update generator.json to use TransformProperties.BoolTypes

* Add stdbool condition from BoolTransformer

Not actually sure if this is ever going to be used, but I guess it will at least be consistent in behavior with BoolTransformer

* Regenerate OpenAL, OpenGL, SDL, Vulkan using Windows

* Add test: TransformPropertiesTests.Transforms_MaybeBool_FieldsAndProperties

* Add test: TransformPropertiesTests.Transforms_Utf8String_StaticConstProperties

* Add note on the bitfield case

* Remove unused ModUtils.MemberIdentifiers()

This was used by the syntax-based renamer (extremely old at this point)

* Add MaybeBoolUtils.MaybeBoolType() factory method
