[ios, macos] Add format expression convenience methods support. (#14094)
Added the ios/macos format expression bindings.
The equivalent is mgl_attributed: or mgl_attributed({}) when making an expression using the expressionForFormat selector.
A new constructor called mgl_expressionForAttributedExpressions:(NSArray<NSExpression*>*)attributedExpressions was added to NSExpression+MGLAdditions category.
Updated the symbol style layer text test to use the bindings.
Updated the Predicates and Expressions.md and For Style Authors.md.ejs template with the bindings.
