Added a Kconfig option that makes the RPA sharing feature optional. By
default, the Zephyr Bluetooth stack now uses the RPA rotation policy
that was active before the introduction of the RPA sharing functionality
in the following PR:
https://github.com/zephyrproject-rtos/zephyr/pull/55449
The new Kconfig option configures the advertising sets linked with the
same Bluetooth identity to use the same Resolvable Private Address in
a given rotation period. After the RPA timeout, the new RPA is
generated and shared between the advertising sets in the subsequent
rotation period.
When this option is disabled, the generated RPAs of the advertising
sets differ from each other in a given rotation period.
