Show desktop preview tool for functions annotated with common preview annotation (#4839)

Allows desktop preview to work with org.jetbrains.compose.ui.tooling.preview.Preview annotation in addition to desktop preview annotation. That allows using preview in common code (#2045), though only with desktop target enabled

Fixes #4839, #2045
