- Fixed the Python method declaration by adding "=..." when a default value was missing. This is legal in a Python stub to not specify the default value.

Since UK2Node_ExecutePythonScript uses wildcards for its pins, it's dependent on its linked inputs. During node reconstruction, we were updating the python node's pins based on incorrect data. For example, one of the input nodes needed to change its pin type from real/double to real/float during reconstruction. However, this reconstruction occurred after the linked python node was reconstructed. As a result, the python node assumed that its linked input node was using a real/double type.
We can fix this by simply changing the priority of UK2Node_ExecutePythonScript to Low_UsesDependentWildcard. Additionally, this change reverts 19482561.

This exposes UObjectBaseUtility's IsPackageExternal() and GetPackage() as
is_package_external() and get_package(), respectively, for UObject instances
that are wrapped to Python. GetOutermost() simply calls through to GetPackage(),
so the newly added get_package() is equivalent to the existing get_outermost(),
but the former is preferred according to the docstring for GetOutermost().
get_outermost() was left in place so as not to break existing Python code.

The latter is used by BP functions, as well as C++ functions that have default arguments that UHT can't parse (eg, a default TMap argument).

The BP compiler erroneously reports that python nodes might be missing implicit casts. However, UK2Node_ExecutePythonScript nodes handle argument slightly differently than conventional function nodes. The pins don't actually correspond to actual arguments on ExecutePythonScript. Instead, they more or less serve as references to their linked inputs, which ExecutePythonScript will pop from the stack and perform a direct conversion to a Python type. As a result, there's nothing to cast, and we can safely remove the entries from the ImplicitCastMap on the current content.

Setters and getters are native functions called by FProperties when setting property values with *_InContainer functions.
Setters and getter function names can be manually specified with Setter = Func and Getter = Func keywords inside of UPROEPRTY macro but they will also be automatically parsed if the name is not explicitly specified if the setter or getter function name matches SetPropertyName and GetPropertyName pattern.
The latter behavior can be disabled in UHT's DefaultEngine.ini by setting AutomaticSettersAndGetters=False.
ImportText and ExportTextItem functions have been deprecated and should be replaced with *_InContainer or *_Direct variants.

- Removed the meta=(MakeStructureDefaultValue= "1,1,1") from the FTransform struct because Unreal Header Tool is already capable to deduce that from the MakeTransform() default C++ prameter.
- Removed the meta=(Scale = "1,1,1") from MakeTransform UFUNCTION because that can be deduced by Unread Header Toold from the default C++ parameter.
Fixed Python code not invoking the a 'Make' function (declared with meta HasNativeMake on a USTRUCT) if no parameters were supplied to Python (ex. unreal.Transform() would not call the MakeTransform(...)).
- In most case, not calling the Make function worked as expected, but the Make function could implement side effects, so always honor it.
Resaved BP macro assets using MakeTransform() with the default values. The default values saved as string with the asset changed from "1,1,1" to "1.000000,1.000000,1.000000" and this triggered a BP Compiler warning.
The following tests were performed:
- In the Blueprint Editor, added a Make Transform node and ensured the default values for scale were (1, 1, 1)
- In the Blueprint Editor, created a User Defined Struct, added as a member a Transform, ensured the default values for the transform scale were (1, 1, 1)
- Added a Python regression unit tests to ensure unreal.Transform() takes the default scale value as (1, 1, 1) if the scale parameter is not provided.
- Created a Blueprint Macro Libraries with a Macro calling MakeTransform() with default parameters, saved it, applied the fix, got the warning, refreshed the node, resaved the macro and ensured the macro used the correct default scale.
