Initialize SystemFontResolver when enabled and make its lifecycle and font-list
population thread-safe.
Use native codepoint fallback matching through Fontconfig on Linux, BSD, and
Haiku, DirectWrite on Windows, and Core Text on macOS and iOS. Preserve the
cached FreeType scan as a fallback when native matching is unavailable.
Enable system fonts by default for UIApplication and warm the font database in
the background. Allow applications to override the policy and disable the
automatic default in the unit-test runner.
Fix glyph fallback checks to respect the resolver's enabled state and add
coverage for concurrent warm-up and shaped symbol fallback.
