Bluetooth: MGMT: add CIS feature bits to controller information

[ Upstream commit 2394186a2cefb9a45a029281a55749804dd8c556 ]

Userspace needs to know whether the adapter has feature support for
Connected Isochronous Stream - Central/Peripheral, so it can set up
LE Audio features accordingly.

Expose these feature bits as settings in MGMT controller info.
