[tracking issue] Change Data Feed read path

Change Data Feed is a feature of the Delta protocol that allows users to scan all row-level changes that happened for each commit.

Tasks

To construct TableChanges, we introduce the LogSegmentBuilder to more easily construct LogSegments.

Generating CDF
[ ] Phase 1: CDF with only add/remove requirements
- Implement iterator to generate action selection vector (this will eventually be the second pass iterator)
- Create visitor to get data from scan files. Scan files are generated from rows that are transformed after log replay.
- Transform rows with CDF information using the expression framework.
[ ] Phase 2: Minimal CDF
- Implement visitor to find cdc actions
- Implement first pass log replay scanner to find cdc actions and commit info.
- Update second pass to mask out all other actions when cdc action is present.
- Build expression to handle cdc files when reading data.
[ ] Phase 3: Deletion vector support
- Collect deletion vectors to resolve add + remove in the same commit. This is done in second phase
- Implement deletion vector difference to find added and removed rows
[ ] Phase 4:
- Perform metadata validation in first pass iterator.
- Handle errors from other delta features such as Column Mapping and V2 Checkpoints
