refactor(metrics): move some metrics from meta to compactor

[Little-Wallace]

Signed-off-by: Little-Wallace bupt2013211450@gmail.com

What's changed and what's your intention?

It's not necessary to collect all metrics info from compactor to meta

• remove metrics in compact_task and report them in compactor directly.
• change level metrics to speed for better observation.

Checklist

• I have written necessary docs and comments
• I have added necessary unit tests and integration tests
• All checks passed in ./risedev check (or alias, ./risedev c)
