enhance: Unify data type check APIs under internal/core (#31800) 
Issue: #22837 

Move and rename following C++ APIs:
datatype_sizeof() ==> GetDataTypeSize()
datatype_name() ==> GetDataTypeName()
datatype_is_vector() / IsVectorType() ==> IsVectorDataType()
datatype_is_variable() ==> IsVariableDataType()
datatype_is_sparse_vector() ==> IsSparseFloatVectorDataType()
datatype_is_string() / IsString() ==> IsDataTypeString()
datatype_is_floating() / IsFloat() ==> IsDataTypeFloat()
datatype_is_binary() ==> IsDataTypeBinary()
datatype_is_json() ==> IsDataTypeJson()
datatype_is_array() ==> IsDataTypeArray()
datatype_is_variable() == IsDataTypeVariable()
datatype_is_integer() / IsIntegral() ==> IsDataTypeInteger()

fix: fix growing index data race and properly handle build error (#31170) 
issue: https://github.com/milvus-io/milvus/issues/31169

also properly handling index build error by re-create a new index so
that nothing will be left in the previous failed index build attempt.

feat: [Sparse Float Vector] segcore to support sparse vector search and get raw vector by id (#30629) 
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.

feat: [Sparse Float Vector] segcore basics and index building (#30357) 
This commit adds sparse float vector support to segcore with the
following:

1. data type enum declarations
2. Adds corresponding data structures for handling sparse float vectors
in various scenarios, including:
* FieldData as a bridge between the binlog and the in memory data
structures
* mmap::Column as the in memory representation of a sparse float vector
column of a sealed segment;
* ConcurrentVector as the in memory representation of a sparse float
vector of a growing segment which supports inserts.
3. Adds logic in payload reader/writer to serialize/deserialize from/to
binlog
4. Adds the ability to allow the index node to build sparse float vector
index
5. Adds the ability to allow the query node to build growing index for
growing segment and temp index for sealed segment without index built

This commit also includes some code cleanness, comment improvement, and
some unit tests for sparse vector.

feat: support search_group_by for milvus(#25324) (#28983) 
related: #25324

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
