Why do we need to include it? It seems ArchiveResource-related functions are not
used in this file.

MHTMLArchive inlines a vector append() so as to require having the full type of
ArchiveResource in scope. We can either "outline" it or revert back to having a
full #include of "ArchiveResource.h" in "MHTMLArchive.h"

I see.  So this include looks wrong to me.
Please do either.

Yes, removed. To make MHTMLArchive.h closed, I moved the definitions of these
helpers to the implementation file.

(Looked over the other #includes of "ArchiveResource.h" added in this CL;
they're needed.)

 #include "platform/mhtml/MHTMLArchive.h"
 #include "platform/weborigin/KURL.h"
 #include "public/platform/WebCString.h"
