Twincpu: Add general multi-core memory access check implementation

Add definitions of multi-core check access data types and HAL APIs.
Implement the general check process for Isolation Level 1 and 2
according to design document [1].
Implement simple check functions based on system memory region
layout. Multi-core platforms can invoke those functions to execute
basic check instead of walking through hardware protection unit
configurations.
