ControlTemplateResult has two members duplicating each other

[YohDeadfall]

Describe the bug

ControlTemplateResult is made as an alias over its parent generic type. The parent type already has Result member of type Control in case of ControlTemplateResult, and ControlTemplateResult adds one more property named Control storing the same value.

Expected behavior

At least Control property must not have a backing field and use Result as the value source. Another option is to remove Control and leave the type mostly empty by using the base implementation.

I thought ControlTemplateResult was supposed to be removed and replaced as part of #6666 (first item which is checked off)

I think it can be just removed, I don't see any critical usages.
