Bluetooth: Add MGMT capability flags for tx power and ext advertising
For new advertising features, it will be important for userspace to know the capabilities of the controller and kernel. If the controller and kernel support extended advertising, we include flags indicating hardware offloading support and support for setting tx power of adv instances. In the future, vendor-specific commands may allow the setting of tx power in advertising instances, but for now this feature is only marked available if extended advertising is supported. This change is manually verified in userspace by ensuring the advertising manager's supported_flags field is updated with new flags on hatch chromebook (ext advertising supported).
