dev-qt/qtwebengine: add IUSE=pdf for QtPdf support in live

Nothing seems too special here, so can just enable it.

Live-only given IUSE=pdf is a default on desktop profiles and will
cause a big unnecessary rebuild (nothing needs QtPdf yet). Note
that QtPdf is fairly trivial (and small'ish) after chromium bits
are already built either way, and does not hurt as a default.

Does require cups at build time (dlopen, left DEPEND-only). May be
possible to be optional but would rather no pdf-only IUSE=cups on
this big package (may revisit if someone wants this).

Would be nicer split (or allow IUSE=-webengine) but, even though the
option exists, build system files note that webengine cannot really
be disabled and then QtPdf still needs parts of chromium to be built
(splitting would cause to rebuild some of the same things twice, but
it is not nearly as big as webengine proper). May revisit.
