Speed up vite-plugin-solid with vite hook filters

[ChristophP]

During our vite build a significant amount of time (44%) is spent in vite plugin solid.

Since rolldown vite plugins can be sped up significantly with hook filters to allow for fewer Rust to JS calls.

By turning this:

export default function myPlugin() {
  return {
    name: 'example',
    transform(code, id) {
      if (!id.endsWith('.data')) {
        // early return
        return
      }
      // perform actual transform
      return transformedCode
    },
  }
}

into this

export default function myPlugin() {
  return {
    name: 'example',
    transform: {
      filter: {
        id: /\.data$/
      },
      handler(code) {
        // perform actual transform
        return transformedCode
      },
    }
  }
}

Backward compatibility

The syntax has supported since vite 6.3+ and could be made backward compatible by leaving the checks in the handlers.
