ArmPkg/ArmDmaLib: assert that consistent mappings are uncached

DmaMap () only allows uncached mappings to be used for creating consistent
mappings with operation type MapOperationBusMasterCommonBuffer. However,
if the buffer passed to DmaMap () happens to be aligned to the CWG, there
is no need for a bounce buffer, and we perform the cache maintenance
directly without ever checking if the memory attributes of the buffer
adhere to the API.

So add some debug code that asserts that the operation type and the memory
attributes are consistent.
