Rename Camera2D's `smoothing` to `position_smoothing`

For Camera2D:
`smoothing_enabled` ->  `position_smoothing_enabled`
`set_enable_follow_smoothing` -> `set_position_smoothing_enabled`
`is_follow_smoothing_enabled` -> `is_position_smoothing_enabled`
`smoothing_speed` -> `position_smoothing_speed`
`set_follow_smoothing` -> `set_position_smoothing_speed`
`get_follow_smoothing` -> `get_position_smoothing_speed`
