Add support to LgWebOSMediaPlayerEntity for video and music

For the LgWebOSMediaPlayerEntity official integration add support on the LgWebOSMediaPlayerEntity.async_play_media to play remote audio and video. It seems something pretty easy and supported by aiowebostv client:

@cmd
    async def async_play_media(
        self, media_type: MediaType | str, media_id: str, **kwargs: Any
    ) -> None:
        """Play a piece of media."""
        _LOGGER.debug("Call play media type <%s>, Id <%s>", media_type, media_id)

        if media_type == MediaType.VIDEO or media_type == MediaType.MUSIC:
            if (source_dict := self._source_list.get("Media Player")) is None:
                _LOGGER.warning(
                    "Source 'Media Player' not found for %s",
                    self._friendly_name_internal(),
                )
                return

            await self._client.launch_app_with_params(
                source_dict["id"],
                {
                    "payload": [
                        {
                            "fullPath": media_id,
                            "mediaType": media_type,
                            "deviceType": "DMR",
                            "fileName": "track",
                        }
                    ]
                },
            )

        elif media_type == MediaType.CHANNEL:
            _LOGGER.debug("Searching channel")
            partial_match_channel_id = None
            perfect_match_channel_id = None

            for channel in self._client.channels:
                if media_id == channel["channelNumber"]:
                    perfect_match_channel_id = channel["channelId"]
                    continue

                if media_id.lower() == channel["channelName"].lower():
                    perfect_match_channel_id = channel["channelId"]
                    continue

                if media_id.lower() in channel["channelName"].lower():
                    partial_match_channel_id = channel["channelId"]

            if perfect_match_channel_id is not None:
                _LOGGER.info(
                    "Switching to channel <%s> with perfect match",
                    perfect_match_channel_id,
                )
                await self._client.set_channel(perfect_match_channel_id)
            elif partial_match_channel_id is not None:
                _LOGGER.info(
                    "Switching to channel <%s> with partial match",
                    partial_match_channel_id,
                )
                await self._client.set_channel(partial_match_channel_id)
