[Profiler] Provide a method to profile Triton XPU Kernel's accuracy execution time.

[chengjunlu]

There is no stand along profiler tools for Triton XPU now.

We used to use:

1. the Torch legacy profiler with the IPEX extension. (This is going to be removed by IPEX)
2. The new torch profiler with the Kineto extended by IPEX. (This depends on the Kineto and Torch)
3. Use the synchronization wait on the host to measure the performance. (This is not accurate with host overheads.)

The Triton has a new component for profiling performance of the Triton kernel. It worth to support it for the Triton XPU.

It is the highest priority for collecting accurate Triton performance data for the coming Triton Demo on Jun 25.

I have added post review comments to the PR that closed this issue, see #1136 (comment).

I am concerned the benchmarks use a different way than the do_bench Triton uses to compute timing.
