feat(watch): support mixed ignored patterns

[Perfecto23]

Summary

Extend watchOptions.ignored to accept string | RegExp | (string | RegExp)[], so framework authors can merge user-supplied RegExp ignores with framework-appended glob ignores in a single array.

This is a Rspack extension for framework composition use cases (see #10596), not webpack watchOptions.ignored parity.

What changed

• Rust watcher data model — new FsWatcherIgnored::Mixed(Vec<FsWatcherIgnoredItem>) variant that matches both glob paths and RspackRegex patterns in a single pass.
• Glob parent-path matching — glob_match_path now walks parent directories so that patterns like **/.cache correctly ignore child paths (e.g. /project/.cache/file.js). This applies to all glob-based ignored variants, not only mixed arrays.
• Native watcher event filtering — Trigger::on_event now checks ignored at the event entry point (via to_string_lossy for non-UTF-8 safety), preventing ignored sub-paths from triggering rebuilds through parent directory association.
• NAPI binding — NativeWatcherOptions.ignored extended to string | (string | RegExp)[] | RegExp with Either4 dispatch.
• Node/watchpack fallback — mixed arrays are normalized into a predicate function: string globs are converted via glob-to-regexp (prebundled) and merged into one RegExp; user RegExp instances are tested individually with lastIndex reset to handle stateful /g /y flags.
• RSC coordinator — client compiler "watch nothing" override changed from () => true to /.*/ to stay compatible with native watcher's function rejection.
• Browser build — added resolve alias for glob-to-regexp in rslib.browser.config.ts, consistent with the existing watchpack alias pattern.
• Tests — new compilerCases/watch-options-ignored.js covering both node and native watcher paths: verifies ignored glob/regex files do not trigger invalid/rebuild, and normal watched files still trigger rebuild.
• Docs — updated English and Chinese watchOptions.ignored docs with mixed array examples; softened glob description to "glob semantics" without referencing the internal implementation.
