Figma Efficiency: Focus State - Create as boolean property

[benjamin-kurien]

Focus is an accessibility parameter that can be used together with almost all other states in the states property.
Hence by providing it as a separate boolean property applied on the layer, it would have the following benefits

• ~ 50% reduction in the number of variants that would otherwise have to be defined. (Because almost all variants except few like hover states can be combined with the focus state)
• Designers have more control on when and where to use focus state on components
• Reduced impact on storage and memory with lesser variants, easier to maintain
