Implement the position delete writer

[ZENOTME]

After we finish #275, we can implement the position delete writer based on this framework.

There is a rust implementation that can be referred to in icelake. But better design is acceptable.

Hi @ZENOTME, can I take on either this task or #341?

Sure! Thanks! Before we move to more writers, maybe we can complete #345 first so that we can add the e2e test for later writers. I will complete it as soon as possible!
