Fix interface mismatch in case "spirv_validation_capabilities_test"

User variable texCoord in location = 3 was only used in VS and FS,
lack of the variable in TCS, TES and GS is causing interface mismatch.

VK-GL-CTS Issue: 2219

Affects: KHR-GL46.gl_spirv.spirv_validation_capabilities_test

Components: OpenGL

Change-Id: I5899906f89efb380896a277939b532f393d00fce
