[WK2][DiskCache] Store common HTTP header names as strings
https://bugs.webkit.org/show_bug.cgi?id=157326
<rdar://problem/26073498>
Reviewed by Antti Koivisto.
Store common HTTP header names as strings in the disk cache instead of
using their value in the HTTPHeaderName enumeration. Having the disk
cache rely in the HTTPHeaderName enumeration is risky becomes it means
the cached data would become invalid every time someone updates
HTTPHeaderNames.in in WebCore. If someone were to update
HTTPHeaderNames.in without bumping the disk cache version, we would end
up with wrongly recognized HTTP header names after loading responses
from the cache.
