UIAnimation Vector related API can be more simpler

[sdcb]

This is related to: #324

Not sure it's easy or not, but according to document: https://docs.microsoft.com/en-us/windows/win32/api/uianimation/nf-uianimation-iuianimationmanager2-createanimationvectorvariable

cDimension should be the sizeof array initialValue, in this case, we should try get array length instead of pass a new parameter.

Like this:
IUIAnimationVariable2 CreateAnimationVectorVariable(double[] initialValue);

And get vector value should have a overload that try return to double[] directly without passing any element,

Like this:

double[] GetVectorValue();

And some Get/Set method API call should be able to change into properties:

Like this:

double PreviousValue { get; }
double[] PreviousVectorValue { get; }

Ok, I figured out it seems the question No.1 can be done by following statement:

<map param="IUIAnimationManager2::CreateAnimationVectorVariable::cDimension" relation="length(initialValue)" />
