Source/WebKit/efl:

Add missing implementation setSerializeHTTPLoads to EFL's
DumpRenderTreeSupport to allow testing resource load order.

* WebCoreSupport/DumpRenderTreeSupportEfl.cpp:
(DumpRenderTreeSupportEfl::setSerializeHTTPLoads):
* WebCoreSupport/DumpRenderTreeSupportEfl.h:

Tools:

Add missing implementation setSerializeHTTPLoads to allow
testing resource load order.

* DumpRenderTree/efl/DumpRenderTreeChrome.cpp:
(DumpRenderTreeChrome::resetDefaultsToConsistentValues):
* DumpRenderTree/efl/LayoutTestControllerEfl.cpp:
(LayoutTestController::setSerializeHTTPLoads):

LayoutTests:

Unskip test cases which rely on LayoutTestController's setSerializeHTTPLoads
implementation and add EFL expectations for tests same as in mac port (MIME
type is "application/javascript" instead of "application/x-javascript").

* platform/efl/Skipped:
* platform/efl/fast/loader/file-protocol-fragment-expected.txt: Removed. The current
result matches the base expectation, so removed the platform-specific results.
* platform/efl/fast/preloader/document-write-2-expected.txt: Added.
* platform/efl/fast/preloader/document-write-expected.txt: Added.
