fix(ble/bluedroid): preserve HCI status on BLE 4.2 GAP failures

Browse Source 
Return BTM_HCI_ERROR | hci_status from legacy BLE 4.2 GAP HCI command
paths instead of mapping failures to BTM_ILLEGAL_VALUE or
BTM_NO_RESOURCES. Add btm_ble_status_from_hci() helper and propagate
real status through scan start/stop completion callbacks.


(cherry picked from commit 47dd785a18)
