Removes the underscored prefixes from the @_section and @_used attributes, making them public as @section and @used respectively. The SymbolLinkageMarkers experimental feature has been removed as these attributes are now part of the standard language. Implemented expression syntactic checking rules per SE-0492. Major parts: - Renamed @_section to @section and @_used to @used - Removed the SymbolLinkageMarkers experimental feature - Added parsing support for the old underscored names with deprecation warnings - Updated all tests and examples to use the new attribute names - Added syntactic validation for @section to align with SE-0492 (reusing the legality checker by @artemcm) - Changed @DebugDescription macro to explicitly use a tuple type instead of type inferring it, to comply with the expression syntax rules - Added a testcase for the various allowed and disallowed syntactic forms, `test/ConstValues/SectionSyntactic.swift`.
