Skip implicit PrimitiveID checks on devices without geometry shader support

Since the fragment shader unconditionally uses gl_PrimitiveID, these
tests must be run on a device with geometry shader support, since a
variable decorated with PrimitiveId in SPIR-V requires one of of the
Geometry or Tessellation features according to the SPIR-V spec.
