Ignore connection indications from peers that are already
connected. This is to bring the behavior of the controller in

"If an advertiser receives a connection request from an initiator it
is already connected to, it shall ignore that request."

Under CONFIG_BT_TICKER_EXT configuration, the ticker interface has been

means that conn and slave ticker start calls can now omit must-expire
default-on configuration, relying on LLL updating the mode as needed.

This commit targets solving issue #17731 over the LL_SW_SPLIT
arch of the BLE stack in Zephyr. This functionality is exposed
to the user as HCI Zephyr Command extensions
- BT_HCI_OP_VS_WRITE_TX_POWER_LEVEL
- BT_HCI_OP_VS_READ_TX_POWER_LEVEL
which enable Tx power read/write operations within BLE radio events
on a per role/connection basis.
The functionality is enabled upon the Kconfig advanced configuration
triggered by
- BT_CTLR_TX_PWR_DYNAMIC_CONTROL
depending on the enablement of Zephyr HCI vendor-specific command
extensions.
Necessary low-level radio HAL functionality and power definitions
are also supplied to address the high-level functionality of
controlling the Tx power.
