VS: Implement CMAKE_GENERATOR_PLATFORM for VS >= 8

For VS generator names that do not specify the platform name, read
CMAKE_GENERATOR_PLATFORM to get it.

Extend the RunCMake.GeneratorPlatform test with a case covering
use of the x64 platform when the test generator is a Visual Studio
generator whose name does not specify a platform.
