mainly changes in three aspects:
1. enable setting group_size for group by function
2. separate normal reduce and group by reduce
3. eleminate uncessary padding in search result for reducing

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.

This PR adds the ability to search/get sparse float vectors in segcore,
and added unit tests by modifying lots of existing tests into
parameterized ones.

Search GroupBy function, used to aggregate result entities based on a
specific scalar column.
several points to mention:
1. Temporarliy, the whole groupby is implemented separated from
iterative expr framework **for the first period**
2. In the long term, the groupBy operation will be incorporated into the
iterative expr framework:https://github.com/milvus-io/milvus/pull/28166
3. This pr includes some unrelated mocked interface regarding alterIndex
due to some unworth-to-mention reasons. All these un-associated content
will be removed before the final pr is merged. This version of pr is
only for review
4. All other related details were commented in the files comparison

1. Support Term, like `A in [1, 2, 3]`
2. Support Not, like `! A < 3`
3. Support logical combination, like `A < 3 && B > 5 or C == 0`

**What type of PR is this?**
- [x] Feature
**What this PR does / why we need it:**
This PR supports boolean expression as DSL.
1. The goal of this PR is to support predicates
like `A > 3 && not B < 5 or C in [1, 2, 3]`.
2. Defines `plan.proto`, as Intermediate Representation (IR)
used between go and cpp.
3. Support expr parser, convert predicate expr to IR
in proxynode, while doing static check there
4. Support IR to AST in cpp, enable the execution
