LibGfx+Fallout: Make ImageDecoder return ErrorOr

Browse source 
...from try_create_for_raw_bytes().

If a plugin returns `true` from sniff but then fails when calling
its `create()` method, we now no longer swallow that error.

Allows `image` (and other places in the system) to print a more
actionable error if early image headers are invalid.

(We now no longer try to find another plugin that can also handle
the image.)

Fixes a regression from #20063 / #19893 -- before then, we didn't
do fallible work this early.
