increased the maximum call depth validated by the GLSL ES compiler,
without increasing the stack size supported by our back-end.

The sw::MAX_SHADER_CALL_STACK_SIZE of the back-end is now statically
passed to an es2::MAX_SHADER_CALL_STACK_SIZE (has to remain equal or
smaller) and then passed to the GLSL compiler's resources limits.
