New function ProtGranularity returns the protection granularity of the operating system. (On all currently supported operating systems this is the same as the granularity of memory mapping returned by VMPageSuze, but it's important to separate these concepts.) MPMCheck asserts that the granularity of memory mapping is a multiple of the granularity of protection.
Client arena supports MPS_KEY_ARENA_GRAIN_SIZE.
Some of the test cases set the arena grain size.
