[compiler] use reactiveConditionHelper to reduce size

[GrinZero]

I found that when studying react compiler, the compiler always compiles scope into very similar conditional comparison code blocks. So I am thinking about whether it is possible to extract these similar code blocks into a common function, which may help reduce the code volume of large-scale projects.

Overview

This PR introduces a new runtime, which I call conditionHelper. It organizes reusable logic in the scope and separates it into common functions to reduce the volume of compiled code. Although this is only an initial implementation and there are still testing and other tasks to be completed, it has a certain positive effect on reducing the volume of compiled code.

Demo

Modifying the babel option allows you to experience helpers, like:

...
  babel: {
    plugins: [
      [
        "babel-plugin-react-compiler",
        {
          environment: {
            enableReactiveScopeConditionHelper: true,
          },
        },
      ],
    ],
  },
...

And run build or dev:
