Inject tcs on gles
With ARB_tessellation_shader it is possible that a TES is given without a TCS. This makes it necessary to inject a pass-through TCS when run on a host that supports only OES_tesselation_shader (or GLES 3.2), because here a program must either contain both, TCS and TES, or none.
This kind of includes !223 (merged)
