[master][PATCH] opencl-cts: add recipe

[a-christidis@ti.com]

From: Antonios Christidis <a-christidis@ti.com>

This recipe provides the opecl-cts suite.  This is a pre-release version
v2024-08-08, which I have tested to work with opencl-headers version v2024.05.08
. The pre-release version was picked due to incompatibility issues with other
versions of headers. Commits past the pre release will run into issues with 
CL_UNORM_INT_2_101010_EXT  

The recipe also includes a patch, to allow it to compile and build properly.
Further information below.

+Subject: [PATCH] Ignore Compiler Warnings
+
+
+Upstream repo is using Ubuntu 20.04 to build. Their compiler is old enough to
+to not catch these warnings. While our distro compiler is capable of catching 
+them, resulting in compilation failures. Thus change the build system to ignore
+the warnings. Resulting in no errors (-Werror flag enabled).  
+
+Upstream-Status: Inappropriate [oe specific - compilation errors due to cross-compiling]
