Support A = Data.define(:a, :b, :c)

[marshall-lee]

Description

Data was added in Ruby 3.2. This is similar to Struct but immutable and with kwargs by default. So this PR aims to support simple Data.define const assignments:

Foo = Data.define(:a, :b, :c)
Foo::Bar = Data.define(:a, :b, :c)
Baz = Data.define(:a, :b, :c) do
  def d; end
end

Note: the support of the class Foo < Data.define(:a, :b) form was not added by intention because I don't want to encourage this style of programming and it does not appear in the Data documentation. If one has a strong opinion that this style must be supported, they're free to do it in a separate PR.

Completed Tasks
