Feature request: allow `ShowkaseColor` and `ShowkaseTypography` also for `@Composable` functions

[francescocervone]

Currently, the @ShowkaseColor and @ShowkaseTypography annotations can be applied only to fields:

• https://github.com/airbnb/Showkase/blob/1.0.0-beta15/showkase-annotation/src/main/java/com/airbnb/android/showkase/annotation/ShowkaseColor.kt
• https://github.com/airbnb/Showkase/blob/1.0.0-beta15/showkase-annotation/src/main/java/com/airbnb/android/showkase/annotation/ShowkaseTypography.kt

Sometimes, you need to declare Colors and TextStyles as composable functions, for example in this case:

// colorResource(...) is a composable function
val brand: Color @Composable get() = colorResource(id = R.color.brand)

It would be nice to be able to apply the @ShowkaseColor and @ShowkaseTypography also to functions, probably the same targets allowed by the @Composable annotation (https://developer.android.com/reference/kotlin/androidx/compose/runtime/Composable), at least for property getters.

Thanks.

I was looking into it just yesterday. I think this should be possible to do if I do some minor refactors. Also related to #115

Hey @vinaygaba ! This feature would still be a great addition imo, do you know if there is a chance it will be considered? Thanks!
