Fix SpirvShader::Interpolate() not handling noperspective

SpirvShader::Interpolate() was using:

flat=false
perspective=true

for all interpolation computations. This broke down in tests
using noperspective inputs. This CL adds logic to pass down
flat and perspective settings to SpirvShader::Interpolate()
so that it uses the correct settings.
