[Piglit] [PATCH] cmake: Add switch for vs_in_64 generator

[Dylan Baker]

This generator takes a long time to run and produces several Gbs of
tests. The right solution in the long term might be to replace the
generator with a C/C++ based solution that generates tests on the fly,
but for now adding a switch to turn it off can help in many situations.

This switch defaults to on so that the default behavior doesn't change.
