refactor: unify runtime globals render modes

[LingyuCoder]

Summary

• introduce RuntimeGlobalsRenderMode for webpack, rspack context, and rspack lexical identifier rendering
• introduce RuntimeTemplateRenderMode to select the module, runtime module, and chunk render-mode combination for each runtime mode
• route module, runtime module, and chunk generation through scenario-specific RuntimeTemplate factory methods
• unify chunk and runtime-module code templates, remove the obsolete runtime-module code mode and boolean rendering flags, and derive legacy runtime module identifiers from the render mode

Refactors runtime template APIs to clarify how runtime globals are rendered across module, runtime-module, and chunk generation scenarios, unifying rspack/webpack render-mode handling.

Changes:

• Replaces the old “runtime code template” with explicit runtime-module vs chunk template factories and render-mode mappings.
• Migrates many plugins/modules from ChunkCodeTemplate / lifetime’d templates to a unified RuntimeCodeTemplate.
• Introduces RuntimeGlobalsRenderMode / RuntimeTemplateRenderMode and updates runtime globals/variables rendering accordingly.
