issue: #29892 This PR 1. Pass Materialized View (MV) search information obtained from the expression parsing planning procedure to Knowhere. It only performs when MV is enabled and the partition key is involved in the expression. The search information includes: 1. Touched field_id and the count of related categories in the expression. E.g., `color == red && color == blue` yields `field_id -> 2`. 2. Whether the expression only includes AND (&&) logical operator, default `true`. 3. Whether the expression has NOT (!) operator, default `false`. 4. Store if turning on MV on the proxy to eliminate reading from paramtable for every search request. 5. Renames to MV. ## Rebuttals 1. Did not write in `ExtractInfoPlanNodeVisitor` since the new scalar framework was introduced and this part might be removed in the future. 2. Currently only interested in `==` and `in` expression, `string` data type, anything else is a bonus. 3. Leave handling expressions like `F == A || F == A` for future works of the optimizer. ## Detailed MV Info  Signed-off-by: Patrick Weizhi Xu <weizhi.xu@zilliz.com>
