Solutions:
- parser (planparserv2)
- add CallExpr in planparserv2/Plan.g4
- update parser_visitor and show_visitor
- grpc protobuf
- add CallExpr in plan.proto
- execution (`core/src/exec`)
- add `CallExpr` `ValueExpr` and `ColumnExpr` (both logical and
physical) for function call and function parameters
- function factory (`core/src/exec/expression/function`)
- create a global hashmap when starting milvus (see server.go)
- the global hashmap stores function signatures and their function
pointers, the CallExpr in execution engine can get the function pointer
by function signature.
- custom functions
- empty(string)
- starts_with(string, string)
- add cpp/go unittests and E2E tests

We use vector of string_view to save data temporally but real string
data will be released after record batch is deconstructed.
Change it to vector of string to avoid memory corruption.

issue #34117
* Refactoring
* Added a capability to perform multiple bitwise `and` and `or`
operations in a single op
* AVX2, AVX512, ARM NEON, ARM SVE backed bitwise `and`, `op`, `xor` and
`sub` ops
* more unit tests for bitset
* fixed a bug in `or_with_count` for certain bitset sizes
* fixed a bug for certain offset values for inplace operations that take
two bitsets

This PR splits sealed segment to chunked data to avoid unnecessary
memory copy and save memory usage when loading segments so that loading
can be accelerated.
To support rollback to previous version, we add an option
`multipleChunkedEnable` which is false by default.

Native support for Google cloud storage using the Google Cloud Storage
libraries. Authentication is performed using GCS service account
credentials JSON.
Currently, Milvus supports Google Cloud Storage using S3-compatible APIs
via the AWS SDK. This approach has the following limitations:
1. Overhead: Translating requests between S3-compatible APIs and GCS can
introduce additional overhead.
2. Compatibility Limitations: Some features of the original S3 API may
not fully translate or work as expected with GCS.
To address these limitations, This enhancement is needed.

* improved `Column.h` to make the code much more readable and
maintainable, and added detailed comments.
* fixed an issue where `ArrayColumn::NumRows()` always returns 0 when
the mmap backing storage is a file.
* removed unused `ColumnBase` constructors and unnecessary members so we
don't get confused.
* Updated `test_chunk_cache.cpp` to make the tests parameterized: to
test both mmap enabled and disabled. Added sparse field in the test to
add coverage.
* re-enabled test `Sealed::GetSparseVectorFromChunkCache`.
* But 2 other disabled tests `Sealed::WarmupChunkCache` and
`Sealed::GetVectorFromChunkCache` remain disabled, there seems to be
errors. @bigsheeper PTAL.

This PR utilizes pk index in segment to exclude non-hit delete record
during load delete records. This ability is crucial when l0/delete
forward policy only replies on segment itself(without BF filtering).
