Spec consistency around param_value_size parameter for many OpenCL procedures

[shajder]

In few cases of OpenCL API spec mentioned that param_value_size is ignored if related para_value is NULL, eg. :

param_value_size specifies the size in bytes of memory pointed to by param_value. This size must be ≥ size of return type as described in the table below. If param_value is NULL, it is ignored.

This is the case for clGetCommandBufferInfoKHR and clGetCommandQueueInfo.

For below, similar cases this information is missing.

clGetPlatformInfo, clGetDeviceInfo, clCreateSubDevices, clGetContextInfo, clGetSupportedImageFormats, clGetImageInfo, clGetPipeInfo, clGetMemObjectInfo, clGetGLTextureInfo, clGetSamplerInfo, clGetProgramInfo, clGetProgramBuildInfo, clCreateKernelsInProgram, clGetKernelInfo, clGetKernelWorkGroupInfo, clGetKernelSubGroupInfo, clGetKernelArgInfo, clGetEventInfo, clGetSemaphoreHandleForTypeKHR, clGetSemaphoreInfoKHR, clGetEventProfilingInfo, clGetMutableCommandInfoKHR, clGetGLContextInfoKHR
