Refactor: Reorganize Form Header controls

[JoshuaHungDinh]

Description

This PR reorders the Header, Heading and Description toggle controls related to the Visual Form Builders Header component. The Reorder was requested to be updated per design and also allows these controls to determine whether or not to show the related TextControls.

In addition, the Form Builder blocks with icons have had their corresponding svg elements replaced with the SVG & Path components provided by WordPress and the NextGen blocks have an updated fill color of currentColor so that the icons are visible when selected from the icon list.

And lastly the Text block has had its title renamed to "Text Field"
