The goal of this patch is to remove the noice we've in the logs:
```

Unfortunately, eslint-plugin-import depends on eslint 9. This plugin doesn't seem to be
actively maintained (lot of open issues and PRs).
Fortunately there's a fork of the plugin that doesn't support eslint 10 yet but is actively maintained.
So this PR changes the eslint version to 10 and replaces eslint-plugin-import with eslint-plugin-import-x.
Instead of having all the code for the new debugger in a single file,
split it into multiple files.
This makes it easier to navigate and maintain the codebase.
It'll be make hacking and fixing bugs in the debugger easier.
It has few cool features:
- all the canvas used during the rendering can be viewed;
- the different properties in the graphics state can be viewed;
- the different paths can be viewed.
In PR 20016 the actual uses of the `enableHWA` option was removed from the viewer, but for some reason it's still being provided when initializing `PDFViewer` and `PDFThumbnailViewer` despite the fact that it's now dead code.
This is consistent with a bunch of other viewer code, since an `AbortSignal` can only be aborted once any "abort" listeners can thus be removed when invoked.
This patch adds right-click support for images in the PDF, allowing
users to download them. To minimize memory consumption, we:
- Do not store the images separately, and instead crop them out of the
PDF page canvas
- Only extract the images when needed (i.e. when the user right-clicks
on them), rather than eagery having all of them available.
To do so, we layer one empty 0x0 canvas per image, stretched to cover
the whole image, and only populate its contents on right click.
These images need to be inside the text layer: they cannot be _behind_
it, otherwise they would be covered by the text layer's container and
not be clickable, and they cannot be in front of it, otherwise they
would make the text spans unselectable.
This feature is managed by a new preference, `imagesRightClickMinSize`:
- when it's set to `-1`, right-click support is disabled
- when set to `0`, all images are available for right click
- when set to a positive integer, only images whose width and height are
greater than or equal to that value (in the PDF page frame of
reference) are available for right click.
This features is disabled by default outside of MOZCENTRAL, as it
significantly degrades the text selection experience in non-Firefox
browsers.
