Extract wildcard check into typesIncludesWildcard helper

- Added typesIncludesWildcard() function in moduleNameResolver.ts
- Updated all wildcard checks to use the helper function:
  - checker.ts: getCannotFindNameDiagnosticForName
  - programDiagnostics.ts: FileIncludeKind.AutomaticTypeDirectiveFile
  - watch.ts: fileIncludeReasonToRelatedInformation
  - resolutionCache.ts: updateTypeRootsWatch
  - jsTyping.ts: discoverTypings
- Added imports in all consuming files

This centralizes the wildcard checking logic and makes the code more maintainable.
