[nrf fromtree] tests: bluetooth: tester: add support for wid 145 and 167

wid 145 requests handle of a UUID of a long characteristic. wid 167
requests to remove the characteristic by handle requested in wid 145.

2 new commands are added to support these wids:
- BTP_GATT_GET_HANDLE_FROM_UUID to request handle of a certain UUID
- BTP_GATT_REMOVE_HANDLE_FROM_DB to remove attribute by handle.
