issue: #43427
This pr's main goal is merge #37417 to milvus 2.5 without conflicts.
# Main Goals
1. Create and describe collections with geospatial type
2. Insert geospatial data into the insert binlog
3. Load segments containing geospatial data into memory
4. Enable query and search can display geospatial data
5. Support using GIS funtions like ST_EQUALS in query
6. Support R-Tree index for geometry type
# Solution
1. **Add Type**: Modify the Milvus core by adding a Geospatial type in
both the C++ and Go code layers, defining the Geospatial data structure
and the corresponding interfaces.
2. **Dependency Libraries**: Introduce necessary geospatial data
processing libraries. In the C++ source code, use Conan package
management to include the GDAL library. In the Go source code, add the
go-geom library to the go.mod file.
3. **Protocol Interface**: Revise the Milvus protocol to provide
mechanisms for Geospatial message serialization and deserialization.
4. **Data Pipeline**: Facilitate interaction between the client and
proxy using the WKT format for geospatial data. The proxy will convert
all data into WKB format for downstream processing, providing column
data interfaces, segment encapsulation, segment loading, payload
writing, and cache block management.
5. **Query Operators**: Implement simple display and support for filter
queries. Initially, focus on filtering based on spatial relationships
for a single column of geospatial literal values, providing parsing and
execution for query expressions.Now only support brutal search
7. **Client Modification**: Enable the client to handle user input for
geospatial data and facilitate end-to-end testing.Check the modification
in pymilvus.

issue: #44156
Enhance FlushAll functionality to support targeting specific collections
within databases instead of only database-level flushing.
Changes include:
- Add FlushAllTarget message in data_coord.proto for granular targeting
- Support collection-specific flush operations within databases
- Maintain backward compatibility with deprecated db_name field
This enhancement allows users to flush specific collections without
affecting other collections in the same database, providing more precise
control over data persistence operations.

issue: #29735
Implement partial field update functionality for upsert operations,
supporting scalar, vector, and dynamic JSON fields without requiring all
collection fields.
Changes:
- Add queryPreExecute to retrieve existing records before upsert
- Implement UpdateFieldData function for merging data
- Add IDsChecker utility for efficient primary key lookups
- Fix JSON data creation in tests using proper map marshaling
- Add test cases for partial updates of different field types

supported.

Issue: #41261
`milvusclient.NewHybridSearchOption` receives a variadic `annRequests`
parameter. However, since `milvusclient.annRequest` is private, there is
no way to declare a slice, therefore there is no way to make it fully
generic (as in, create a slice of `milvusclient.annRequest`s and pass
them to `NewHybridSearchOption`. This PR renames
`milvusclient.annRequest` to `milvusclient.AnnRequest` to export it.
This is an API change since it's renaming a struct. However, since the
struct was previously private no external code depends on it, unless
it's doing nasty things with reflection (in which case it should not
depend on the name).
