x_mem_resp_t type needs to be expanded with debug trigger match information

Created by: Silabs-ArjanB

If a debug trigger with 'before timing (mcontrol.timing=0)' has been configured on the data address of an offloaded load or store, then such load/store shall not be allowed to complete in case of a trigger match. The coprocessor (which would normally have been told that it was allowed to commit such load/store already) needs to be informed of such trigger match and that the instruction is not allowed to complete.

The proposal is to add this information to the x_mem_resp_t type.
