With the deprecation of `BT_LE_ADV_OPT_USE_NAME` and
`BT_LE_ADV_OPT_FORCE_NAME_IN_AD` the tester has been updated to not use
the macro adding the device name in the advertising/scan response data
anymore. Instead the name was explicitly added to the scan response
data. But because that part of the tester was using an extended
advertiser and was already adding data in the AD, the name should have
been put in the advertising data and not the scan response data.
The same issue apply to both `btp_cap.c` and `btp_bap_broadcast.c`,
update them to add the device name in the advertising data.
