b12e070b - [OpenCL] Set KHR extensions minimum version to OpenCL 1.0 (2nd try) (#176681)

[OpenCL] Set KHR extensions minimum version to OpenCL 1.0 (2nd try) (#176681) Motivation is similar to 25cfdaa4e9dc. Their spec don't specify a required OpenCL version. Targets may expose them before OpenCL 1.2. Set KHR extensions (depth images, mipmaps, subgroups, kernel clock, dot product, ext_float_atomics, extended_bit_ops, cles_khr_int64) to availability 1.0. Changes to opencl-c.h: * Relax header and test guards to allow extension macros whenever any OpenCL C version is defined. * Relax cl_khr_depth_images guard to allow cl_khr_depth_images, OpenCL C++, or OpenCL C 2.0+, since image2d_depth_t and image2d_array_depth_t types require that coverage. * Guard image1d_t, image1d_array_t and image2d_array_t types with OpenCL C++ or OpenCL C 1.2+ to match with OpenCL C spec. Relates to https://github.com/KhronosGroup/OpenCL-CTS/pull/2376. Update: The first attempt was reverted in #175993, but the regression described in #175993 should be fixed in ROCm/llvm-project's opencl-c.h.
