In #41548, I show that I would like to provide an object with images in
getStaticProps. The StaticImageData is parsed correctly and provided as
a prop to the page. Nonetheless, the image is not available in the
static directory. Therefore the image is not shown. This is also
addressed in issue #29571. The underlying cause is that the import of
the image is removed from the client bundle and only present in the
server bundle.
Evaluating the next-image-loader shows that the file is only placed in
the static directory if emitted from the client bundle by firing
this.emitFile. By changing this to only emitting the file from the
serverside bundle in the webpackloader, static images loaded in the
getStaticProps are made available properly as well as images directly
used in componts (so present in server and client bundle).
This would PR would prevent the circumventing solution which enforces
that the StaticImageData should be present in the client side bundle
while it will also be present in the staticprops.

This PR updates the `next/future/image` component so that CSS `filter` is never needed. Previously, we used SVG to blur for prod and CSS to blur for dev, but now we use SVG for both.
This required a shared function `getImageBlurSvg()` used between both client and server because `next dev` doesn't create Data URIs and instead defers blur generation until request time. So we also need to defer svg generation to request time (on the server) during next dev.
This is the first step to removing `<noscript>` completely (see #39736).
This PR is a follow up to PR #39190 so that we can dynamically set the `feComponentTransfer` when we know the image doesn't have transparency (at this time its just jpeg).
We also set the stdDeviation to 1 and the viewbox to the placeholder's width/height to avoid any rounding issues.
Finally, we also fix the conversion from `objectPosition` to `backgroundPosition` because they have different default values according to the spec.
This will ensure an image hashed consistently regardless of how its imported:
- `import file from "./file.png"` -> /_next/static/media/file.12345678.png
- `url(./file.png)` -> /_next/static/media/file.12345678.png
- `new URL("./file.png", import.meta.url)` -> /_next/static/media/file.12345678.png
Follow-up to https://github.com/vercel/next.js/pull/29307 this ensures the `blurDataURL` is correctly prefixed with the `basePath` in development since we use the `_next/image` endpoint to generate the placeholder in dev mode.

This ensures we prefix the `src` for static images with the `basePath` correctly, this also copies over the static image tests to the basePath image-component suite.

This PR changes the implementation of `placeholder=blur` when using `next dev` so that it lazy loads on-demand.
This will improve the developer experience for web apps with many blurred images.
fixes#26607
This change makes it so the image loader plugin only emits a file while processing an image import for the client. The final generated image URL was already the same in SSR and CSR anyway, so this change doesn't have any functional impact.
I also changed the name of the static page in the image component tests, since it was causing some conflicts with the static assets folder.
There are strict conditions for using `placeholder=blur` documented in #25949 but this will give the user a better understanding during `next dev` and links to the error.
- Error when `placeholder=blur` and no `blurDataURL`
- The Error for small images with `placeholder=blur` has been changed to a warning
- Added support for blurring a webp image
- Added error page linking to relevant docs
