Investigate returning pointers to const in ManagedMemoryResource public API

### What

The MangedMemoryResource public interface has functions returning pointers to non-const. Some of these functions (e.g. GetBaseAddress()) should return pointers to const, since the calling code should not be modifying the region before getUsableBaseAddress (since this is reserved for bookkeeping by the SharedMemoryResource). Other functions such as getUsableBaseAddress() should return pointer to non-const, since the calling code uses this pointer to write to shared memory.

We should check all functions in the interface returning a pointer and decide whether they should be const or non const.

DoD:
Remove suppression for autosar_cpp14_m9_3_1_violation in SharedMemoryResource::getBaseAddress()
Change ManagedMemoryResource API to return pointer to const where required.
