There are regions of virtual memory that start below the WoW user address limit but end beyond it (e.g. a large empty region between the end of 32-bit allocations and 64-bit ntdll). When queried from WoW via `NtQueryVirtualMemory(MemoryBasicInformation)`, the returned struct for such a region will have `BaseAddress + RegionSize` past the highest user address (or even worse - it may overflow 32 bits). These patches make WoW `NtQueryVirtualMemory` report a truncated size for such regions, so that they appear to end exactly at the highest user address. This fixes programs that, e.g., walk their address space using iterated calls to `VirtualQuery`.
Also, make `MemoryRegionInformation` queries return `STATUS_INVALID_PARAMETER` when passed an address beyond the user address limit, like `MemoryBasicInformation` already does.
