Source/WebCore: Limit -apple- and -khtml- to ENABLE(DASHBOARD_SUPPORT)

Reviewed by Eric Seidel.

As recommended by David Hyatt in
<https://lists.webkit.org/pipermail/webkit-dev/2010-July/013536.html>,
we should phase out support for -khtml- and -apple- vendor prefixes in
CSS (in favor of -webkit-).

As noted in <https://bugs.webkit.org/show_bug.cgi?id=42093#c29>, Dave's
proposal is a bit too agressive.  These prefixes appear to be needed
for a number of dashboard widgets.  For that reason, this patch limits
the prefixes to ENABLE(LEGACY_CSS_VENDOR_PREFIXES).

This patch enables ENABLE(LEGACY_CSS_VENDOR_PREFIXES) on apple-mac and
apple-win, which will let us learn whether removing these prefixes
causes a compatibility problem on the broader web.

Skip these two tests, which are testing that -apple- and -khtml- vendor
prefixes work correctly.
