This huge commit is a nearly complete rewrite of the Dolphin search
code. It implements most of the improved Dolphin search UI/UX as
designed and discussed in a collaborative effort by Kristen McWilliam,
Jin Liu, Andy Betts, Tagwerk, a few others and me.
See https://invent.kde.org/system/dolphin/-/issues/46.
# Notable changes
- A toggle to change the search tool is provided as most contributors
deemed that useful in
https://invent.kde.org/system/dolphin/-/merge_requests/642#note_985112.
- The default search is changed to filenamesearch for maximum
reliability.
- Removing all search parameters will take users back to the view state
prior to starting a search instead of keeping the search results open.
- The UI for choosing file types or modification dates has been made
more powerful with more granularity and more options.
- Most search parameters can be configured from a popup menu which
gives us extra space for extra clarity.
- Labels and help buttons as well as hyperlinks to settings makes sure
the user always knows why some search parameters are unavailable in
some contexts.
- Chips show important search parameters while the popup is closed.
They allow quickly removing filters.
- The titles of the search and the input field placeholder message
change to make clear whether file names or file contents are searched.
- When the user actively switches the search tool, whether content
should be searched, or whether to search everywhere, this is preserved
for the initial state of the search bar when the user opens it the next
time after restarting Dolphin.
# Architecture
- The new DolphinQuery class is independent of the UI and contains all
search parameters modifiable in Dolphin as easy setters and getters.
- DolphinQuery objects are also used to update the states of every
component in the search UI. There is now a clear separation of UI and
search configuration/DolphinQuery.
- DolphinQuery is responsible for exporting to and importing from
search URLs.
- The search UI always reflects the currently configured DolphinQuery
no matter if the user changed the UI to change the DolphinQuery or
loaded a DolphinQuery/older search URL which then is reflected in the
UI.
- I tried to simplify all classes and their interaction between each
other as much as possible.
- I added some tests

Before this commit pressing the free space button when Filelight
is not installed would show a singular action called "Install
Filelight to View Disk Usage Statistics…". Pressing this button
would open the store page for Filelight. This is an okay user
experience, but we can do better.
This commit makes it so pressing the free space button when
Filelight is not installed shows an attractive UI that makes clear
that freeing up disk space can be accomplished nicely by installing
Filelight. The "Install Filelight…" button on this UI is connected
to PackageKit directly, so we do not need to show a separate store
like Discover and instead trigger an installation right then and
there. For this, the recently introduced DolphinPackageInstaller
KJob is used.
Installation progress is reported through the status bar similar to
the progress reporting of slowly loading directories or searches.
Installation failure or success is ultimately shown within Dolphin
as a passive notification above the view.
On Microsoft Windows or when PackageKit is not available, the
install button will only open a store page for Filelight.

use KRecentFilesAction like Kate and others to signal used
files/dirs
could later be used to plug-in a recently used menu, too,
if ever wanted
avoids that this dependency could be missed and the functionality
is not there, too

This commit adds a guided setup that leads users from a situation
in which they try to "sudo dolphin" towards them successfully
setting up and using kio-admin.
1. When users enter "sudo dolphin", they are told to start Dolphin
by typing "dolphin --sudo" or "dolphin --admin" instead.
2. When Dolphin is started with "--sudo" or "--admin" it checks
whether an "admin" protocol is installed. If not, a guided
setup leads users towards installing it.
3. After that, Dolphin starts with an installed "admin" protocoll
like kio-admin. Now a non-modal information dialog appears that
explains how to activate and use kio-admin.

When one instance of Dolphin activates another it passes a startupId (X11) / activation token (wayland) along.
On X11 this is passed using the DESKTOP_STARTUP_ID environment variable. The code tries to read that through KStartupInfo::startupId().
That doesn't work though, since Qt at startup reads the environment variable afterwards. However, it is nice enough to allow us to access
it through QX11Info::nextStartupId(). Use that to read the token in the first instance and pass it to the second instance like we do on Wayland
The user-facing impact of this is minimal since KStartupInfo::setNewStartupId internally falls back to KWindowSystem::forceActiveWindow when no
startupId is passed.

This way we get a build time warning if the var isn't defined at all, e.g.
a missing check_include_files() CMake call.
