fbc4255f - [clang-tidy] Teach `modernize-type-traits` about more type traits (#147074)

[clang-tidy] Teach `modernize-type-traits` about more type traits (#147074) These new traits come from various standard versions: C++14: - `tuple_element_t` C++17: - `is_placeholder_v` - `is_bind_expression_v` - `ratio_equal_v` - `ratio_not_equal_v` - `ratio_less_v` - `ratio_less_equal_v` - `ratio_greater_v` - `ratio_greater_equal_v` - `is_error_code_enum_v` - `is_error_condition_enum_v` - `is_execution_policy_v` - `tuple_size_v` - `variant_size_v` - `uses_allocator_v` - `variant_alternative_t` C++20: - `compare_three_way_result_t` - `common_comparison_category_t` - `unwrap_ref_decay_t` - `unwrap_reference_t` C++23: - `is_implicit_lifetime_v` C++26: - `is_nothrow_relocatable_v` - `is_replaceable_v` - `is_trivially_relocatable_v` - `is_virtual_base_of_v` This doesn't add `treat_as_floating_point_v` or `is_clock_v` because they require more invasive changes; instead I've opened #147072 to track them.
