index desktop views by qscreen instead of id, making ScreenPool
the single source of truth for the mapping between screen names
and ids. This is less error prone and easier to consistency check
(if view->screenToFollow() is ever different to its has key it will
assert)
The whole logic of screen management is moved to ScreenPool.
ShellCorona will have to never call QGuiApp->screens, but only trust what ScreenPool it's telling it
Also adds an autotests on screenpool which makes a fake wayland server which sends screen added/removed/changed events
Summary: BUG: 390499
Test Plan:
See callgrind in bug report
Added debug in the relevant section, unplugged a monitor. Saw my output

ECM, when requiring ECM >=5.38, sets CMAKE_*_OUTPUT_DIRECTORY, so the
tests executables are no longer generated in the current binary dir.
Calling add_test() with the signature
add_test(<name> <command> [...])
will not result in any further processing of the <command> argument,
it will be executed as is. Using instead
add_test(NAME <name> COMMAND <command> [...])
will result in <command> getting some handling, cmp. CMake docs:
"If <command> specifies an executable target (created by add_executable())
it will automatically be replaced by the location of the executable
created at build time."
Which is what is needed now here (and also used in ecm_add_test).
Summary:
this replaces the approach with the expose event in
20b439a4f4 by directly monitoring the xcb screen change
notify native event
Test Plan:
attaching and detaching the external screen on a laptop
configured to deactivate the internal screen upon connection
same behavior as D3777

Summary:
We used to append them, but that didn't work well and was crashing plasmashell
on fresh start.
A default desktop would be created alongside with the one provided by the
layout instead of replacing it.
If a layout wants to provide an additional screen for a desktop in the secondary
screen, it should specify the screen.
Test Plan:
Now the plasmashell tests pass. In fact I noticed it was broken due to an e-mail
Jonathan sent me that the test on neon was timing out. The test in neon will
freeze when the test crashes. Probably something to look into.
It can be reproduced by running:
```
xvfb-run -a --server-args="-screen 0 1024x768x24" dbus-launch --exit-with-session <exec>
```
Where `exec` is the process we need to run.
Now the test passes.
It's a crash that I had reproduced locally in the past. I can't now.
