kbe 302da5f3c2 task 1.4: add NativeMethods.cs LibraryImport P/Invoke surface
Add LibraryImport-based P/Invoke declarations for all required Win32
APIs: OpenProcess, CloseHandle, ReadProcessMemory, WriteProcessMemory,
VirtualAllocEx, VirtualProtectEx, VirtualFreeEx, CreateRemoteThread,
GetThreadContext, SetThreadContext, Wow64GetThreadContext,
Wow64SetThreadContext, LoadLibrary, GetProcAddress, and
WaitForSingleObject.

Add InternalsVisibleTo WhiteMagicTest so the test project can call
internal NativeMethods.

Tests (NativeSurfaceTests): 7/7 passing.
