Bluetooth: controller: preserve TX power

Preserve the TX power set with the `BT_HCI_OP_VS_WRITE_TX_POWER_LEVEL`
command for advertising and scanning procedures. As the TX power is no
longer overwritten on procedure start, the TX powers can now be set
before starting the procedure. This eliminates the chance for the first
transmissions to use the default TX power instead of the request TX
power.

Similar changes are not made to the connection advertising powers as
changing the TX power for a connection to device A should not change
the TX power for a future connection to device B using the same
`struct lll_adv` instance.

Fixes #27921.
