Add metrics around block commit, block traces, and CCC

[vyzo]

As the tile suggests, this adds 3 metrics for tracking timings and providing visibility around Block commit and CCC:

• The first metric is the aggregate time taken to commit a block
• The second metric is the time taken to compute the trace for a single tx
• The third metric is the the time taken to run CCC for a single tx trace

Please bump version in params/version.go

Other operations to consider:

• Result handling in resultLoop (including rawdb.WriteBlockRowConsumption).
• One additional tracing + CCC call in commit.
• w.collectPendingL1Messages in commitNewWork.
