@KevinZK Can you review it from "NSS" support perspective, if this refactoring code is ready for the future NSS enhancement?

[KevinZK]

Based on the NSS features I have designed so far, I make some suggestions:
For this component to fully support the NSS style, you need to split the KPIProgressItem component as much as possible.
For example, we can split KPIProgressItem into three components _TitleComponent, _SubtitleComponent, and _circleProgressComponent.
After designing like this, the configuration code for NSS will be generated in the ~style.fiori.swift file.

extension KPIProgressItemNSSStyle {
    struct ContentNSSStyle: KPIProgressItemStyle {
        let kpiProgressItemConfiguration: KPIProgressItemConfiguration
        let nssData: NSSStyleData
        func makeBody(_ configuration: KPIProgressItemConfiguration) -> some View {
            KPIProgressItem(configuration)
                .modifier(NSSStyleModifier<NSSBaseStyleType>(styles: self.nssData))
            // Add custom nss style for its content
            // .modifier(NSSStyleModifier<<#T: NSSCovert & RawRepresentable#>>(styles: <#T##NSSStyleData#>)
        }
    }

    struct TitleNSSStyle: TitleStyle {
         let kpiProgressItemConfiguration: KPIProgressItemConfiguration
        let nssData: NSSStyleData

        func makeBody(_ configuration: TitleConfiguration) -> some View {
            Title(configuration)
                .modifier(NSSStyleModifier<NSSBaseStyleType>(styles: self.nssData))
            // Add custom nss style for Title
            // .modifier(NSSStyleModifier<<#T: NSSCovert & RawRepresentable#>>(styles: <#T##NSSStyleData#>)
        }
    }

struct SubtitleNSSStyle: SubtitleStyle {
         let kpiProgressItemConfiguration: KPIProgressItemConfiguration
        let nssData: NSSStyleData

        func makeBody(_ configuration: SubtitleConfiguration) -> some View {
            Subtitle(configuration)
                .modifier(NSSStyleModifier<NSSBaseStyleType>(styles: self.nssData))
            // Add custom nss style for Subtitle
            // .modifier(NSSStyleModifier<<#T: NSSCovert & RawRepresentable#>>(styles: <#T##NSSStyleData#>)
        }
    }

    struct CircleProgressNSSStyle: ProgressStyle {
        let kpiProgressItemConfiguration: KPIProgressItemConfiguration
        let nssData: NSSStyleData

        func makeBody(_ configuration: CircleProgressConfiguration) -> some View {
            CircleProgress(configuration)
                .modifier(NSSStyleModifier<NSSBaseStyleType>(styles: self.nssData))
            // Add custom nss style for Circleprogress
            // .modifier(NSSStyleModifier<<#T: NSSCovert & RawRepresentable#>>(styles: <#T##NSSStyleData#>)
        }
    }
}
