Support auto-accessors

[dsherret]

Describe the feature

TypeScript 4.9 (released on Tuesday) supports auto-accessors:

class Person {
    accessor name: string;

    constructor(name: string) {
        this.name = name;
    }
}

It would be nice if swc supported this keyword.

Babel is also missing this feature. They've started working on it here: babel/babel#15209

FWIW, TypeScript has just made the accessor keyword a modifier under a property declaration. Maybe a quick first pass might just be to add a boolean property for this to PropertyDeclaration https://ts-ast-viewer.com/#code/MYGwhgzhAEAKCmAnCB7AdtA3gKGn6Yww8UKi0aYAtvAFzQQAuiAlmgOYDc2u+w6TRAFdgjMgApKNeoLbsAlFl758jABYsIAOinxoAXgrV43FQF9sZoA

@kdy1 I think this one can be closed? I noticed this seems to be supported now (thanks!)

The parser is implemented but I'm still working on transforms

Closing in favor of #7193
