GetterProp - Add type_ann

[dsherret]

Adds parsing of a type annotation to GetterProp.

This is valid typescript:

const obj = {
    get test() : string {
        return "";
    }
};

The pr seems good to me, but I expect swc_ecma_transforms to be broken.

Can you give me a permission to push to your fork? I'm asking this as I don't like breaking master branch. (Although tracis ci fails, I always check that all tests passes locally)

[dsherret]

@kdy1 that would be great! I believe you already have permission. to push to my fork. Thanks and no rush!

@dsherret I didn't know that I have push permission on fork. I fixed swc_ecma_transforms and verified that all tests pass.
