[Research] Variant support

Research how to implement proper variant support to be able to create vanilla release and change customization just by switching the variant.

Areas to study:

• Support State Syntax
• Detect if a State Variant is found in the Variant name syntax
• If a State Variant is found keep track of id’s in each Variant
• If id’s match keep track of property changes
• Create States in qds and apply property changes to the correct State
• If a merge template is known (Button) and a state is know (Hover) add the correct when condition

• Detect if Theme Variant is found in the Variant name syntax
• If Theme Variant is found and Colours use the Style name, keep track of which theme is applied
• Apply the correct id in each case, or apply the appended id generated in creating the library style

• Detect if another non-qml Variant is defined (Brand)
• Keep track of id’s and property changes between id’s
• Either a) creates states with Variants full syntax
  (Brand=QDS > brand-qds and Brand=Creator > brand-creator)
  Or b) Create Components with variants value appended.
