Repurpose mangling operator `Y` as an umbrella operator that covers new attributes on function types. Free up operators `J`, `j`, and `k`. ``` async ::= 'Ya' // 'async' annotation on function types sendable ::= 'Yb' // @Sendable on function types throws ::= 'K' // 'throws' annotation on function types differentiable ::= 'Yjf' // @differentiable(_forward) on function type differentiable ::= 'Yjr' // @differentiable(reverse) on function type differentiable ::= 'Yjd' // @differentiable on function type differentiable ::= 'Yjl' // @differentiable(_linear) on function type ``` Resolves rdar://76299796.
