1c50d61a5a libavutil/hwcontext_opencl: Fix channel order in format support check
The `opencl_get_plane_format` function was incorrectly determining the
value used to set the image channel order. This resulted in all RGB
pixel formats being set to the `CL_RGBA` pixel format, regardless of
whether or not they actually *were* RGBA.

This patch fixes the issue by using the `offset` and depth of components
rather than the loop index to determine the value of `order`.

61cb505d18 lavu/opencl: replace va_ext.h with standard name
Khronos OpenCL header (https://github.com/KhronosGroup/OpenCL-Headers)
uses cl_va_api_media_sharing_intel.h. And Intel's official OpenCL driver
for Intel GPU (https://github.com/intel/compute-runtime) was compiled
against Khronos OpenCL header. So it's better to align with Khronos.

7faae6e745 hwcontext_opencl: DRM to OpenCL mapping for ARM
Using cl_arm_import_memory.  Unfortunately, despite this not being a
standard extension, the function clImportMemoryARM() is not accessible
via clGetExtensionFunctionAddressForPlatform().  This means that it has
to be linked directly to the ARM OpenCL binary, so making a portable
binary is not possible as it is with all other mapping extensions.
