Bluetooth: MGMT: report BIS capability flags in supported settings

Bluetooth: MGMT: report BIS capability flags in supported settings

[ Upstream commit 348240e5fa901d3d4ba8dffa0e2ba9fc7aba93ab ]

MGMT_SETTING_ISO_BROADCASTER and MGMT_SETTING_ISO_RECEIVER flags are
missing from supported_settings although they are in current_settings.

Report them also in supported_settings to be consistent.
