Removes the ElectricAction for ShowDashboard and the relevant code
in screenedges and the KCM.
Also a leftover in the glide effect.

Basically dead code given that Plasma doesn't have a dedicated dashboard
mode anymore and also doesn't set the required window role for it to
work.
By deleting we save one string comparison for each newly opened window.

Following the approach how it's done for X11: only create the interface
if the shader succeeded to compile and remove support again if it failed
to compile after a reconfigure.

before, hiding the buttons relied on the effect
seeing a paint event for the (with a low timeline
value) what's too wonky at least for instant animations
(certain failure) or when effect exits immediatey
(due to screen edge invocation issues or whatever)

Theory:
----------
because PresentWindowsEffect::screenCountChanged() is shortcut
for "if (!isActive())", but the desktopgrid doesn't call
PresentWindowsEffect::setActive (or at least
PresentWindowsEffect::screenCountChanged), so the effect can
"miss" the increasing screen count change (it sees the signal,
but ignores it) and when desktopgrid calls it, it assumes the
m_gridSizes array is big enough (but it isn't)
Steps:
----------
1. effects are loaded, 1 screen present
2. 2nd screen gets added, but inactive effects ignore that
3. desktop grid gets activated, updates according to screen count,
calls presentwindows for screen #2
4. presentwindows data is only prepared for one screen from step 1
=> BOOM

the (old) button effect windows used to be unreferenced
with the re-invocation of the effect. because we stopped
deleting/recreating the window, this approach failed and
the effect window was never deleted.
Unreferencing the window at proper occasion (see new hide
location) coked up - guess what - the exact same "texture is
junk" issue as for the QtQuick close button in present windows...
So we resort to the exact same stupid "hide by moving" solution
as we have there.

Without the componentDisplayName the shortcut dialog takes the name of
the application e.g. Systemsettings or "KDE Control Module", but we want
it to be KWin.
REVIEW: 124706
If the user has only maximized windows or all
windows crammed into one region of the screen
the effect would not resemble an aperture at all
this ensures a maximum amount of corners is used
while seeking to still use shortest paths

a) close to pointless
b) the target resolution texture is invalid if the resize effect is enabled (as the window was not actually resized)

transformed screens prevent hardware clipping
leading through filtering subquads
This requires to subquad in the painting pass
what is not supported for non rectangular
qauds ands presently aborts (in debug builds)
if any quad is transformed (as by eg. the wobbling)

Same issue as with present windows closers: qml is slow
Interestingly "hide" means "hide" here and there're also
no visual artifacts.
