This reverts commit fd04fe04c0.
This change wasn't technically wrong, but presents an awkward developer
API until the point where we can port *all* PlasmaComponents to their
upstream QQC2 versions, and as such, it was premature.
Basically:
- PlasmaExtras.Heading -> Kirigami.Heading
- PlasmaComponents3.Label -> QQC2.label
We can do this because these components only existed in the past to use
special Plasma colors, but no visual styling. And the color stuff is
obsolete because Kirigami colors work correctly in Plasma now.
Everything was tested with a dark Plasma theme and a light color scheme
to ensure no regressions.
We use KWIN_NAME, KWIN_INTERNAL_NAME_X11 and KWIN_INTERNAL_WAYLAND
properly only in a few places. In other, we use hardcoded names.
Let's not bother and hardcode kwin names everywhere rather than have one
foot in and one foot out, it's simpler.
This allows to toss a large amount of custom rendering code.
Furthermore, it removes the build-time dependency on Plasma Framework
for FrameSvg and Theme from KWin core as it's pulled in through QML
imports now.
It also cleans up the API and removes functions that are effectively
unused or no-op after this change.
For instance, effects often destroy their effect frames
in pre/postPaintScreen, which would now destroy an `OffscreenQuickView`,
which changes GL context. This is alleviated by delaying detruction
of the internal view.
Support for the features of text cross-fade and selection frame,
which are not used by any of the built-in effects, is dropped.

Once in a while, we receive complaints from other fellow KDE developers
about the file organization of kwin. This change addresses some of those
complaints by moving all of source code in a separate directory, src/,
thus making the project structure more traditional. Things such as tests
are kept in their own toplevel directories.
This change may wreak havoc on merge requests that add new files to kwin,
but if a patch modifies an already existing file, git should be smart
enough to figure out that the file has been relocated.
We may potentially split the src/ directory further to make navigating
the source code easier, but hopefully this is good enough already.
