ASoC: bt-sco: fix duplicate DAPM widget names for wideband DAI

The bt-sco-pcm-wb DAI uses the same stream_name strings as bt-sco-pcm
("Playback" and "Capture"). This causes duplicate DAPM AIF widget
names within the same component, leading to debugfs warnings:

  debugfs: 'Playback' already exists in 'dapm'
  debugfs: 'Capture' already exists in 'dapm'

Give the wideband DAI distinct stream names ("WB Playback" and
"WB Capture") and add corresponding DAPM AIF widgets and routes for
them.
