The cl_khr_depth_images associated macro definition is defined twice in
the compiler: in opencl-c.h and automatically by the compiler deduced
from the cl-ext list. These two co-exist and there is no need to remove
cl_khr_depth_images from the cl-ext list.
If we remove cl_khr_depth_images from the cl-ext list, and we do not
include opencl-c.h the macro is not defined.
This fixes conformance test ./test_compiler compiler_defines_for_extensions
when using Comgr with -include opencl-c-base.h -fdeclare-opencl-builtins
without including opencl-c.h.
Before we got the error `ERROR: Supported extension cl_khr_depth_images
not defined in kernel`
This change is needed to eventually get rid of the opencl-c.pch that is embedded in comgr, and that makes implementing a compilation cache in comgr hard.
