feat: add rollup:react-compiler task

[stipsan]

Allows shipping React Compiler output as a separate conditional export condition:

{
  "type": "module",
  "exports": {
    ".": {
      "source": "./src/index.ts",
      "react-compiler": {
        "source": "./src/index.ts",
        "default": "./dist/index.react-compiler.js"
      },
      "require": "./dist/index.cjs",
      "default": "./dist/index.js"
    }
  }
}

There are a few intentional limits:

• The react-compiler condition only supports ESM output, no CJS.
• The compile target for react-compiler sets browser targets, not node, as compiled code is supposed to run in the browser (during SSR, or react server component rendering, there is no lifecycles and thus no need to memoize).
• You have to specify a source condition in the react-compiler condition, even if it's the same as the parent source. I left todos in the code for where we need to implement support for a shorthand: "react-compiler": "./dist/index.react-compiler.js" version.

There's a new root configuration reactCompilerOptions, that applies both if the react-compiler export condition is used, or if the babel.reactCompiler = true option is used.
It's mostly useful to specify a logger.logEvent to see what the compiler is skipping, and for what reason.
