VS10: stop build on custom command error (#11533)

In VS9 and previous versions, :VCReportError is the goto label
to jump to after a failed custom command. It stops the build
before it tries to go any further.

In VS10, :VCEnd is the correct label to use.

Create a method in the VS generators to provide the correct
line of script to use for each version of Visual Studio.

For more internal details, search for VCEnd in the
C:\Program Files\MSBuild directory.
