Speed up vite-plugin-solid with vite hook filters

[ChristophP]

During our vite build a significant amount of time (60+%) 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.
https://rolldown.rs/apis/plugin-api/hook-filters

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.

Implementation

Would you be interested in a PR for this change?

[brenelz]

Yeah I think we'd be open to a PR around this

@brenelz I provided an implementation in #337 . Let me know if anything needs fixing. There is backward compatibilty, so this should be good for a minor/patch release.
