The fixup pass for delegates in UMG bindings had faulty logic for determining the name of a function. The "FunctionName" field on the binding may not actually reflect the true name of the function. For example, a function rename can make this field stale. This would eventually cause BP compilation errors since we didn't find the matching function graph(s) that needed fixup.
Instead, we should call GetMemberName on the final path segment. This will use a GUID for determining what the actual function name is.

The original ENABLE_BLUEPRINT_REAL_NUMBERS macro was strictly meant for AB testing in the Dev-LWC. Currently, disabling it won't work, and would likely lead to broken behavior. Its presence might incorrectly indicate to licensees that this is an option that can be toggled safely.

Blueprint real number support.
This change deprecates the use the of "float" and "double" types in Blueprints in favor of a new "real". By default, "real" is back by a double precision floating point number. However, it can be single precision if the number is a native float property or function parameter. This distinction won't be visible to the Blueprint user: in both instances, they'll be represented by "real" pin types. During deserialization, we'll automatically convert Blueprint pin types to use real/doubles, unless they're used to represent native code (including delegate signatures).
One consequence of this change is that we need to perform implicit casts between single and double precision real numbers. During Blueprint compilation, the compiler will detect points in the graph for when either a widening or narrowing conversion needs to occur. Subsequently, the script bytecode will contain a new cast instruction that performs the conversion. This also works on container types, but each entry in the container will have to be converted. This can introduce unwanted overhead for large containers that are frequently passed between Blueprint and native code.
The scope of this change affects Blueprints used by Gameplay, Animation, Control Rig, and UMG.
