[mac] tracking supported channel mask (#2838)

This commit contains the following changes:
- Adds new logic to `Mac` to track supported channel mask along
  get/set methods.
- Adds public OT APIs `otLinkGetSupportedChannelMask()` and
 `otLinkSetSupportedChannelMask()` to get/set the channel mask.
- Ensures supported channel mask from `Mac` is included in Dataset
  TLVs when a local Dataset is generated.
- Ensures the channel mask at `Mac` gets updated when a new Dataset
  configuration is applied.
- Adds `OT_CHANGED` notification for signaling channel mask changes.
- Updates `NcpBase` and `PHY_CHAN_SUPPORTED` spinel property get/set
  handlers to adopt the new public APIs.
- Updates `NcpBase` to emit async `PHY_CHAN_SUPPORTED` updated on
  OT_CHANGED channel mask notification.
