[TASK] Benchmark existing timestamp functions that work in non-UTC time zone (non-DST)

[NVnavkumar]

Now that:

#9802
#6834
#9801
#9815
#6842

have all been merged, we need to measure performance with a non-UTC timezone to ensure that there are no major performance issues with this new functionality. Here is the list of functions/expressions that have been updated:

• from_utc_timestamp
• to_utc_timestamp
• GpuHour
• GpuMinute
• GpuSecond
• from_unixtime
• unix_timestamp
• date_format

We should measure performance for all of these functions. The idea would be to post the results in this issue for reference, and file any follow-up issues to fix performance. See #10100 for an example of performance results and potentially some other approaches, but really choose any approach that can give definitive answers for performance on the GPU.
