VS: Teach VS >= 10 to recognize CMAKE_SYSTEM_NAME 'Android'

When CMAKE_SYSTEM_NAME is 'Android', check for an installation of
'NVIDIA Nsight Tegra Visual Studio Edition' and generate .vcxproj
files for the "Tegra-Android" platform.  Also make the installed
version available in a CMAKE_VS_NsightTegra_VERSION variable.
