Bluetooth: Impmlement extended adv enable

Browse Source 
This patch basically replaces legacy adv with extended adv
based on the controller support. Currently there is no
design change. ie only one adv set will be enabled at a time.

This also adds tx_power in instance and store whatever returns
from Set_ext_parameter, use the same in adv data as well.
For instance 0 tx_power is stored in hdev only.
