Vlad Ureche 88af8fa0b1 Show candidates for names not in scope
This commit adds functionality that allows the name resolution pass
to search for entities (traits/types/enums/structs) by name, in
order to show recommendations along with the errors.

For now, only E0405 and E0412 have suggestions attached, as per the
request in bug #21221, but it's likely other errors can also benefit
from the ability to generate suggestions.
