Richard Wei fb66de6126 Unify mangling operators for async, @Sendable, @differentiable and @noDerivative.
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
```
