drivers/wifi, mb/google: Drop config `WIFI_SAR_CBFS`

Now that SAR support in VPD is deprecated in coreboot, there is no
need for a separate Kconfig `WIFI_SAR_CBFS` as the SAR table is only
supported as a CBFS file. This change drops the config `WIFI_SAR_CBFS`
from drivers/wifi/generic/Kconfig and its selection in
mb/google/.../Kconfig.

wifi_sar_defaults.hex is added to CBFS only if
CONFIG_WIFI_SAR_CBFS_FILEPATH is not empty because current mainboards
do not provide a default SAR file in
coreboot. Thus, CONFIG_WIFI_SAR_CBFS_FILEPATH is updated to have a
default value of "".
