Update version from 9.0.0 to 9.0.40 to align precisely with MAUI 9.0.40 release. Update CHANGELOG, package metadata, and templates. Fix thread safety issue in FontFallbackManager by changing _glyphCache from Dictionary to ConcurrentDictionary to prevent race conditions during concurrent glyph lookups.
