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

var has more than one meaning.
This PR add `AllPartitionsID` to replace these usages in delete
scenarios.

The conan version used in all the setup scripts was updated to `1.61.0`
in https://github.com/milvus-io/milvus/pull/27870. However, a line in
the developer documentation was left out.
Since the dependencies no longer install correctly with conan `1.58`
(https://github.com/milvus-io/milvus/issues/27869), all documentation
should consistently use the updated version.
