graphics/kcolorpicker: Update to 0.3.0

graphics/kimageannotator: Update to 0.7.0

Flavorize both ports for qt5 and qt6 variants and update consumers.

While here, drop several unused deps for graphics/gwenview.

Mk/Uses: always use colon for build/run suffix

Most USES use a colon for build/run(/test) suffixes. Change kde.mk,
qt.mk and pyqt.mk to do the same, and update all ports using that.

Remove WWW entries moved into port Makefiles

Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.

This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

Add WWW entries to port Makefiles

It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.

Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.

There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.

kde-ports: remove runtime-dependency on Qt testlib

Qt testlib is a library for tests; it is not generally needed
at runtime. Move it to a _build dependency for the KDE-related
ports that use it for their tests.

Update graphics/kcolorpicker to latest upstream release

There's no release notes, but the 6 commits since the previous
release are mostly documentation and licensing changes. The library
is now LGPLv3+ licensed (previously the Makefile said GPLv2, which
applied to releases up to and including 0.1.1 of this software).

Fix build on GCC-based systems by adding c++11-lang to USES:

  CMake Error in CMakeLists.txt: The compiler feature "cxx_decltype" is not
known to CXX compiler "GNU" version 4.2.1.

New Port: graphics/kimageannotator and graphics/kcolorpicker

This is a future dependency for graphics/spectacle.
