Ensure DRAIN_ACTION_FLUSH_AND_UPDATE_DRM_SESSION is always executed

Browse source 
`codecDrainAction` is set to `DRAIN_ACTION_NONE` in 3 places in
`MediaCodecRenderer`:
* The constructor (so there's no prior state to worry about)
* `updateDrmSessionV23()`: Where `mediaCrypto` is reconfigured based
  on `sourceDrmSession` and `codecDrmSession` is also updated to
  `sourceDrmSession`.
* `resetCodecStateForFlush()`: Where (before this change) the action
  is unconditionally set back to `DRAIN_ACTION_NONE` and so any
  required updated implied by
  `DRAIN_ACTION_FLUSH_AND_UPDATE_DRM_SESSION` is not done.

This change ensures that `flushOrReleaseCodec()` handles
`DRAIN_ACTION_FLUSH_AND_UPDATE_DRM_SESSION` before calling .

This probably also resolves Issue: google/ExoPlayer#10274
