bors bad50269f8 Auto merge of #147602 - JohnTitor:dedup-lifetime-capture-errors, r=estebank 
Deduplicate higher-ranked lifetime capture errors in impl Trait

  Previously, when an `impl Trait` captured multiple higher-ranked
  lifetimes from an outer `impl Trait`, the compiler would emit a
  separate error for each captured lifetime. This resulted in verbose
  and confusing diagnostics, especially in edition 2024 where implicit
  captures caused duplicate errors.

  This commit introduces error accumulation that collects all capture
  spans and lifetime declaration spans, then emits a single consolidated
  diagnostic using MultiSpan. The new error shows all captured lifetimes
  with visual indicators and lists all declarations in a single note.

r? `@estebank`
