feat: add option to control using proto text name as key during URL encoding

[demoManito]

Description (what this PR does / why we need it):

• binding.EncodeURL and form.EncodeValues and form.EncodeFieldMask add form.EncodeOption, used to control whether to use proto text name as key when encoding. and it will not affect the original logic
• cmd/protoc-gen-go-http add the -prototext_encodeurl parameter to control whether to use the json tag defined in proto as the key when encoding. The default is false and will not change the original generated code logic. (example: kratos proto client api/test.proto -- --go-http_opt=prototext_encodeurl=true)

func (c *GreeterHTTPClientImpl) SayHello(ctx context.Context, in *HelloRequest, opts ...http.CallOption) (*HelloReply, error) {
	var out HelloReply
	pattern := "/helloworld/{name}"
-	path := binding.EncodeURL(pattern, in, true)
+	path := binding.EncodeURL(pattern, in, true, form.Encode().UseProtoTextAsKey(false))
	opts = append(opts, http.Operation(OperationGreeterSayHello))
	opts = append(opts, http.PathTemplate(pattern))
	err := c.cc.Invoke(ctx, "GET", path, nil, &out, opts...)
	if err != nil {
		return nil, err
	}
	return &out, nil
}

Please take a look at this if you have time @shenqidebaozi. For users, there will be deviations in the use of EncodeURL. There are already multiple issues that have feedback on this.

[shenqidebaozi]

Why do we need to separate this package? It looks strange to see it here

[demoManito]

It's true that a single package doesn't make much sense, it's already moved out @shenqidebaozi

Is it necessary to process in encoding and can it be processed in gen code

[demoManito]

Is it necessary to process in encoding and can it be processed in gen code是否需要在编码中处理，是否可以在 gen code 中处理

What does gen code mean? Since the code specifies using json name as a parameter, it seems that only this method will not affect the previous compatibility @shenqidebaozi
