resolve: Convert ambiguous_glob_imports lint into a hard error

[petrochenkov]

I'm tired of this logic interfering with any attempts to fix or refactor glob imports.

The lint was implemented 2.3 years ago, and made deny-by-default and report-in-dependencies 4 months ago.

The removal is a bit over-eager because of one piece that wasn't implemented correctly (#113099 (comment)), but I want to look at the crater results.

Closes #114095.
