The existing feature exchange procedure does not give the proper
response as specified in the BT core spec 5.0.
The old behaviour is that the feature-response returns the logical and
of the features for both peers.
The behaviour implemented here is that the feature-response returns the
featureset of the peer, except for octet 0 which is the logical and of
the supported features.
Tested by using the bt shell, and having different featuresets
on the 2 peers.

Update LLCP handling during PHY update and Data Length update to not
start the LL control procedure if the remote has already indicated that
the procedure is not supported.
This fulfills the following requirement from the BT Core Specification
(Core_v5.2, Vol 6, Part B, Section 4.6):
Except where explicitly stated elsewhere in this specification, if the
peer Link Layer has indicated either during a feature exchange procedure
or by responding with an LL_UNKNOWN_RSP PDU that it does not support a
procedure, then the Link Layer shall not use that procedure.
Re-use the connection parameter request handling for PHY and
data length update procedures.

When a must-expire ticker callback is executed, it is important not to

Fix infinite recursion in host-based bt_rand function. This would call
HCI LE Random Number command, which would in turn call bt_rand, causing
an infinite recursion.
bt_rand -> prng_reseed -> BT_HCI_OP_LE_RAND -> le_rand -> bt_rand
To solve this issue the controller should avoid doing calls into the
host, so all calls to bt_rand in the controller should be replaced with
a call to a controller function.

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.
