Native window decorations: cleaned-up/simplified JetBrains Runtime custom window decorations "enabled" checking:

Browse Source 
- `FlatSystemProperties.USE_WINDOW_DECORATIONS` is now also used for JBR custom window decorations
- `FlatSystemProperties.USE_JETBRAINS_CUSTOM_DECORATIONS` is now only used to disable JBR custom window decorations; then FlatLaf native window decorations are used
- JBR custom window decorations are now disabled when running in JetBrains Projector, Webswing or WinPE
