Revert 291007 "Set response headers for data URL."

> Set response headers for data URL.
> 
> Resources represented by a data URL will stay being considered to be
> unique origin resource but are changed to allow cross origin access by
> the Access-Control-Allow-Origin header.
> 
> We take this approach mainly because we want scripts in an iframe with
> a data URL specified to its src attribute to be executed as a script on
> a unique origin resource, not on the parent frame.
> 
> We can choose to treat "loading" of data URL specially as same origin
> while execution as different origin. But such an approach complicates
> security policy checking algorithm.
> 
> Grammar checking code is added to ensure we emit a valid content-type.
> 
> Blink side CL https://codereview.chromium.org/54173002/ will be landed
> first to temporarily disable layout tests that will break, and then
> this CL will be landed.
