feat: add RuntimeNormalModuleTask

[hyf0]

Description

          I'm intending to not include `runtime` module as the part of making module graph. In this way, we don't need to write such code.

Another way is to have a special ModuleTaskForRuntime to deal with the special logic of runtime module.

I haven't think through which way is better. Let's change it later.

We should have should have different kind of module task to deal with different module. This prevent mixing up code for different module.

For example, runtime module would never call load or resolve hooks.

Test Plan
