### What problem does this PR solve?
Issue Number: resolve
Problem Summary:
On macOS with Homebrew, CMake may find a versioned protobuf installation
while
a generic dependency include path, such as `/opt/homebrew/include`, appears
before the protobuf include directory.
If that prefix contains headers from another protobuf installation, generated
sources are compiled against headers that do not match the selected `protoc`
and protobuf library. This causes errors such as:
This file was generated by a newer version of protoc ...
### What is changed and the side effects?
Changed:
- Put `${PROTOBUF_INCLUDE_DIRS}` ahead of generic dependency include paths in
`brpc_common_config`.
- Keep generated protobuf headers first, followed by the selected protobuf
installation and then other project/dependency headers.
Side effects:
* Performance effects:
None. This only changes CMake header search order.
* Breaking backward compatibility:
None.
* * *
