Show built keys by rule in ghcide-bench summary

[crtschin]

Closes #5052.

Makes the following changes:

• Use table-layout to print the tables.
• There were some discrepencies between the csv and stdout outputs.
  • Fixes avgPerRespT in stdout, which was present in the csv but omitted in stdout
  • Fixes 1stBuildT in stdout, which didn't include firstResponseDelayed which the csv did.
• Outputs per-rule build histogram for each benchmark.

Example output of ghcide-bench tables now
