Kitex does not guarantee that generated dependency package aliases will be unique

[shanezhiu]

Describe the bug
There is a Project Structure:
reporoot/
idl
│   └── protobuffer
│   ├── base
│   │   ├── packagea
│   │   │   └── v1
│   │   │   └── examplea.proto
│   │   └── packageb
│   │   └── v1
│   │   └── exampleb.proto
│   └── example
│   └── v1
│   └── combine.proto

the file conbine.proto imports examplea.proto and exampleb.proto both.

after I do a generate action, kitex -type protobuf -I . idl/protobuffer/example/v1/combine.proto,

there are import package conflicts in generated stubs, like this：

client.go
import (
	"context"
	client "github.com/cloudwego/kitex/client"
	callopt "github.com/cloudwego/kitex/client/callopt"
	v1 "kitexidltest/kitex_gen/base/packagea/v1"
	v1 "kitexidltest/kitex_gen/example/v1"
)

combine.pb.go


import (
	"context"
	"kitexidltest/kitex_gen/base/packagea/v1"
	"kitexidltest/kitex_gen/base/packageb/v1"

	"github.com/cloudwego/prutal"
)

Expected behavior

the genertor guarantee that generated dependency package aliases will be unique

compare protobuffer-go/protoc-gen-go and kitex/proto-gen-go implementions，Kitex potentially lacks the implementation to ensure uniqueness.

Thanks for the feedback. We will fix it. Temporarily, you can define different go_package to solve it.
