Better error for module-resolver, maybe?

Saw a todo when I was poking around in #2131

i think it would help if all errors include the specifier & fromfile.
recently had the error an addon tried to import from "@embroider/virtual", but it,s not one of its explicit dependencies
not hepful.
it was power-select. which has peer deps, when those are not installed, that error appears

Gonna close this as its way out of date now, and the errors we have with vite are pretty good
