[ti-chi-bot]

This is an automated cherry-pick of #10139

What problem does this PR solve?

Issue Number: close #10143

What is changed and how it works?

• allow to custom memory quota for redo;
• allow to custom redo event cache;
• disable redo event cache by default.

Why disable redo event cache by default?

Redo event cache is expected to reduce CPU and I/O usage for TiCDC. However, under a heavy workload cache hit ratio is usually 0, which means the cache doesn't make any help.

In future, maybe we can generate sink/redo tasks based on changefeeds instead of tables. Then we can enable redo cache again.
