[SYCL][joint matrix] add missing licence to test and add combination-based query

Please, update also sycl/sycl/test-e2e/Matrix/XMX8/element_wise_all_ops.cpp, as after switching to common.hpp for other .cpp files and corresponding .hpp file, test in XMX8 folder will stop compiling.
Also despite it is temporary disabled, it passes for me locally, so it can be verified anyway that your changes are correct.

LGTM

Test requires further changes after discussion with author

[YuriPlyakhin]

LGTM, one nit comment.

@dkhaldi there is a post-commit failure. There are two errors:

/Users/runner/work/llvm/llvm/src/sycl/source/detail/queue_impl.hpp:747:64: error: unused parameter 'Type' [-Werror,-Wunused-parameter] void finalizeHandler(HandlerType &Handler, const CG::CGTYPE &Type,

/__w/llvm/llvm/src/sycl/source/detail/queue_impl.cpp:325:24: error: lambda capture 'Context' is not used [-Werror,-Wunused-lambda-capture] 325 | [&Context, &CheckEvent](const sycl::event &Event) {

@martygrant, should I address the errors in this PR or open a new one?

[martygrant]

@dkhaldi apologies I should have detailed that. Yes please create a new PR for the fix, and leave a comment here to the new PR, thank you!

Sounds good, thanks!
It is weird that I cannot see these errors when building locally using
python /iusers/dkhaldi/workspaces/syclos/llvm/buildbot/compile.py

[dkhaldi]

Also, these errors should not be caused by my PR as I don't touch this file.
My PR is a simple change to self-contained tests.

@dkhaldi apologies you are correct. These fails are coming from the last PR to be merged - #11758 the same errors are in its post-commit run - https://github.com/intel/llvm/actions/runs/7697466128. I will comment on that PR to notify the author.
