Esteban Küber d9ab4ff9a3 Remove blanket silencing of "type annotation needed" errors
Remove blanket check for existence of other errors before emitting
"type annotation needed" errors, and add some eager checks to avoid
adding obligations when they refer to types that reference
`[type error]` in order to reduce unneded errors.

// Test that (for now) we report an ambiguity error here, because

// matching. This behavior should likely be improved such that this
// test passes. See #21974 for more details.
