feat(protoc-gen-go-http): add bind query to disable BindQuery

[yeqown]

Description:

This PR introduces a new bind_query flag to the protoc-gen-go-http plugin, allowing users to disable the automatic generation of BindQuery logic in HTTP handlers. This provides finer control over query parameter binding, especially in cases where it's unnecessary or undesired.

Key Changes:

• Added bind_query CLI flag to main.go default true to keep backward compatibility
• Propagated bindQuery parameter through generateFile, generateFileContent, and genService
• Updated httpTemplate.tpl to conditionally include BindQuery logic
• Extended methodDesc struct to include BindQuery field
