resource: Fix SVG and similar resource handling

The validation of if we could process the image (resize etc.) was moved up in Hugo 0.37, which meant SVG and other "non-processable" images would fail.

This commit fixes that by creating a regular resource for these image formats. They will not have `.Resize` or any of the other image methods.

Fixes #4455
