Support several ts signature types

[MasatoDev]

pub enum TSSignature<'a> {
    TSIndexSignature(Box<'a, TSIndexSignature<'a>>),
    TSPropertySignature(Box<'a, TSPropertySignature<'a>>),
    TSCallSignatureDeclaration(Box<'a, TSCallSignatureDeclaration<'a>>),
    TSConstructSignatureDeclaration(Box<'a, TSConstructSignatureDeclaration<'a>>),
    TSMethodSignature(Box<'a, TSMethodSignature<'a>>),
}

✅TSPropertySignature

this signature is already supported.

type Person = {
    name: string;
    age: number;
};

const person: Person = { name: "hoge", age: 30 };

✅TSIndexSignature

type StringDictionary = { [index: string]: string };

const myDict: StringDictionary = {
    name: "hoge",
};
