feat: add option to remove video source on destroy

- Introduced a new static property REMOVE_SRC_WHEN_DESTROY in Artplayer to control whether the video source should be removed when the player is destroyed.
- Updated the destroy method in Artplayer to conditionally remove the video source based on the new property.
- Removed the line that sets the video source to an empty string in the Template class's destroy method, as this is now handled in Artplayer.
- Updated TypeScript definitions to include the new REMOVE_SRC_WHEN_DESTROY property.
