API documentation where Chinese and English were mixed together in
function descriptions, parameter explanations, and return values.
Changes:
- media: media_player, media_recorder, media_session, media_policy
- bluetooth: bt_a2dp, bt_hfp, bt_spp, bt_gap, bt_hid
- network: wapi
- media_utils: add missing media_player_dump and media_recorder_dump APIs (zh-cn + en)
