Source/WebCore:

* CMakeLists.txt:
* DerivedSources.make:
* WebCore.xcodeproj/project.pbxproj:
* Modules/fetch/DOMWindowFetch.js: Removed.
* Modules/fetch/FetchRequest.js: Removed.
* Modules/fetch/WorkerGlobalScopeFetch.js: Removed.
Remove builtin files.

* Modules/fetch/DOMWindowFetch.cpp:
(WebCore::DOMWindowFetch::fetch):
* Modules/fetch/DOMWindowFetch.h:
* Modules/fetch/DOMWindowFetch.idl:
* Modules/fetch/WorkerGlobalScopeFetch.cpp:
(WebCore::WorkerGlobalScopeFetch::fetch):
* Modules/fetch/WorkerGlobalScopeFetch.h:
* Modules/fetch/WorkerGlobalScopeFetch.idl:
Remove builtin and instead create FetchRequest in the implementation.

* Modules/fetch/FetchBody.cpp:
(WebCore::FetchBody::extract):
* Modules/fetch/FetchBody.h:
* Modules/fetch/FetchBodyOwner.cpp:
(WebCore::FetchBodyOwner::extractBody):
* Modules/fetch/FetchBodyOwner.h:
* Modules/fetch/FetchResponse.cpp:
* Modules/fetch/FetchResponse.h:
Rename FetchBody::BindingDataType to FetchBody::Init to match its IDL naming.

* Modules/fetch/FetchHeaders.cpp:
(WebCore::appendToHeaderMap):
(WebCore::fillHeaderMap):
(WebCore::FetchHeaders::create):
(WebCore::FetchHeaders::fill):
* Modules/fetch/FetchHeaders.h:
Add helpers to implement the fill algorithm for various input types.
Leave the existing fill for now, as it is still used by the FetchResponse
builtin, but will eventually be removed.

* Modules/fetch/FetchRequest.cpp:
(WebCore::FetchRequest::initializeOptions):
(WebCore::FetchRequest::initializeWith):
(WebCore::FetchRequest::setBody):
(WebCore::FetchRequest::create):
(WebCore::FetchRequest::setBodyFromInputRequest): Deleted.
* Modules/fetch/FetchRequest.h:
Migrate builtin code to the implementation. This is 1-to-1 re-implementation,
so I did not attempt to fix any conformance issues. That will come in follow up.

* Modules/fetch/FetchRequest.idl:
Replace builtins with an IDL constructor.

* Modules/fetch/FetchRequestInit.h:
* Modules/fetch/FetchRequestInit.idl:
Add missing headers and body to FetchRequestInit.
