asNativeMediaMetadataBuilder

Creates a builder object for a platform-specific MediaMetadata compatible with the underlying media player, pre-populated with data from the current AstroMediaItem.metadata.

This function creates a new MediaMetadata.Builder object and likely uses conversion methods to populate the builder with the corresponding metadata fields from the current AstroMediaMetadata object. The specific conversion logic is likely not documented here, but it presumably translates the data from AstroMediaMetadata to a format compatible with the underlying media player's MediaMetadata class.

The resulting builder object allows further customization of the MediaMetadata before building the final object using build().
