feat(inverted_index.search): add index applier

[zhongzc]

I hereby agree to the terms of the GreptimeDB CLA

What's changed and what's your intention?

Introduce IndexApplier to apply the predefined predicates to the data read by the given index reader, returning a list of relevant indices.

Applier instances are reusable and work with various InvertedIndexReader instances, avoiding repeated compilation of fixed predicates such as regex patterns.

Checklist

• I have written the necessary rustdoc comments.
• I have added the necessary unit tests and integration tests.

Good job! A few suggestions attached.
Another suggestion: maybe we can add some benchmarks for inverted index performance to get a baseline and prepare for future improvements.

Agreed. I will construct some bench cases with local files as the baseline in the upcoming PRs.
