[meta-arago][scarthgap][PATCH v4 1/2] meta-arago-test: add recipe opencl-cts

[<a-christidis@ti.com>]

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

Adding recipe for opencl-cts, v2024-08-08 is a pre-release version.
I have tested it to work with opencl-headers version v2024.05.08 . This version
is picked due to incompatibility issues with other versions of headers.

This is a backport from meta-openembedded, they rejected to move opencl-cts to
scarthgap due to their LTS procedure. New packages do not get merged into LTS
branches after 7 months of the branch creation.

This recipe also comes with a patch.

Within the cmake build system, the compiler -Werror flag is enabled.  This
turns all warnings into errors and doesn't allow the system to compile
correctly.  Change the system to ignore the 3 warning rules that show up when
compiling.
