[Controls] Inline Editor for Control Group

[ThomThomson]

Feature
An inline editor for the control group embeddable should be written to accomplish the following:

• Reordering of Controls
• Changing the control style
• Setting width for all controls at once

Additionally, a generic inline editor should be written to handle:

• Setting the title of an individual control
• Setting the width of an individual control
• Displaying controls for the specific embeddable type - for instance, this editor should contain the editor for the options list control [Controls] Create Edit Mode Experience for Options List Control #108292

To access the editors for individual controls, an edit button should be added to the generic Control Frame.
