Is there an existing issue for this?

• [X] I have searched the existing issues

Describe the problem

Duplicate preview annotations are defined in multiple places for example:

@Preview(name = "phone", device = "spec:shape=Normal,width=360,height=640,unit=dp,dpi=480")
@Preview(name = "landscape", device = "spec:shape=Normal,width=640,height=360,unit=dp,dpi=480")
@Preview(name = "foldable", device = "spec:shape=Normal,width=673,height=841,unit=dp,dpi=480")
@Preview(name = "tablet", device = "spec:shape=Normal,width=1280,height=800,unit=dp,dpi=480")

These configurations are repeatedly used in InterestsScreen, AuthorScreen, TopicScreen. Using Multipreview annotation can simplify the repeated definitions.

Describe the solution

Define an annotation class for DevicePreviews like:

@Preview(name = "phone", device = "spec:shape=Normal,width=360,height=640,unit=dp,dpi=480")
@Preview(name = "landscape", device = "spec:shape=Normal,width=640,height=360,unit=dp,dpi=480")
@Preview(name = "foldable", device = "spec:shape=Normal,width=673,height=841,unit=dp,dpi=480")
@Preview(name = "tablet", device = "spec:shape=Normal,width=1280,height=800,unit=dp,dpi=480")
annotation class DevicePreviews

and replace the existing preview definitions.
