[CI] Move nightly SYCL benchmarking into a separate workflow (#19280)

Performance of SYCL has regressed a lot recently, causing nightly to
fail consistently. However, if nightly is constantly failing, people may
start to ignore nightly. intel/llvm#18766 should
help with the amount of failures, but I am still figuring out the best
parameters to use here, and additionally often times regressions are
caused by driver changes, which is out of intel/llvm's control. Thus,
for future's sake, it might be best to move benchmarking out of
sycl-nightly.yml.

This PR moves nightly benchmarking into its own workflow/nightly job,
1hr before sycl-nightly.yml, in order to reduce the amount of failures
in sycl nightly.
