Allow semicolon or line break as delimiter in object literal type

[golopot]

Typescript object literals types can be written in 3 styles. Currently only comma delimiter is recognized (and trailing comma does not work):

type foo = {
  a: number;
  b: number;
}

type foo = {
  a: number,
  b: number,
}

type foo = {
  a: number
  b: number
}
