Remove the ENABLE_XSLT compile-time flag.

Remove the ENABLE_XSLT compile-time flag.

This mostly mechanical patch shouldn't have any web-visible effect; XSLT has
been enabled for quite some time. The only non-mechanical bits of this patch
are the drive-by additions of "// namespace WebCore" to the closing braces
of a few XSLT files that I noticed while dropping "#endif" statements.

This is a fairly mechanical patch to drop the XSLT compile-time flag, which
we've had enabled forever.

WDYT, oh great reviewers?
