nimble/ll: Add API to set controller public address

Browse Source 
ble_ll_set_public_addr() can be used to set controller public address.
This API can be called in e.g. hal_bsp_init() to set public address
loaded from some vendor specific location. Address set in this way will
take precedence over address configured in syscfg or stored in HW.

NOTE: This is *NOT* intended to be used to modify public address on
already running device. Using it for such purpose may yield unknown
results.
