Feature #14778: Make Object#dup accept a block

I'd like to use `Object#dup` with a block, which is equivalent to `dup.tap`.

An example for `dup.tap` is here.

```ruby
require 'uri'

module MyUri
  class << self
    def foo_uri
      base_uri.dup.tap { |e| e.path = '/foo' }
    end

    private

    def base_uri
      @base_uri ||= URI.parse('http://example.com')
    end
  end
end
```

With this patch, we can write `base_uri.dup { |e| e.path = '/foo' }` and it's simpler.
