Rollup merge of #134284 - estebank:issue-74863, r=lcnr

Keep track of patterns that could have introduced a binding, but didn't

When we recover from a pattern parse error, or a pattern uses `..`, we keep track of that and affect resolution error for missing bindings that could have been provided by that pattern. We differentiate between `..` and parse recovery. We silence resolution errors likely caused by the pattern parse error.

```
error[E0425]: cannot find value `title` in this scope

LL |     if let Website { url, .. } = website {
   |            ------------------- this pattern doesn't include `title`, which is available in `Website`
LL |         println!("[{}]({})", title, url);
   |                              ^^^^^ not found in this scope
