playground: Support tikv-worker and --tikv.columnar in tidb-cse mode

[breezewish]

What problem does this PR solve?

What is changed and how it works?

When --mode=tidb-cse, a fully functional tikv-worker process will be started as well (with remote compactor, remote cop and schema manager running).

Additionally, when --tikv.columnar is specified in this mode, TiKVColumnar query will be enabled (this brings all TiFlash Compute Node to read via TiKVColumnar).
