Two Application Launcher shortcut entries, both nonfunctional

SUMMARY
Choosing to switch the global theme and selecting the checkbox to apply the associated desktop layout duplicates the "Activate Application Launcher" shortcut under the "Plasma" category. One of the duplicates has the default Alt F1 set for the meta key to function but the other is blank. This results in an unusable meta regardless of which one is set to Alt F1.

STEPS TO REPRODUCE
1. Select any theme in Global Themes in System Settings
2. Choose to apply the desktop layout with the checkbox
3. Attempt to activate application launcher with meta key

OBSERVED RESULT
Application Launcher does not respond to meta key as the keyboard shortcut is now duplicated with no easy way to remove one

EXPECTED RESULT
Only one Application Launcher shortcut entry is present at any time under keyboard shortcuts. It either stays bound to alt f1 or is unbound (if the creator of the theme really intended to) with a way to rebind it.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Arch - fully up to date as of 6/1/21, clean install for testing
KDE Plasma Version: 5.21.5
KDE Frameworks Version: 5.82.0
Qt Version: 5.15.2

ADDITIONAL INFORMATION
This issue was also present on Fedora KDE. The default key bindings also have no meta key functionality yet KDE comes with this out of the box. This should probably be remedied as well.

I wonder if this could be one of the causes of Bug 391322.

Take active screen in account and remove shortcut requirement for activating launcher

With the information about the active screen we can make an educated
guess about where the attention of the user is and where they could
expect the launcher to open. If on the screen no launcher could be
activated, look at all launchers. Also remove the requirement for
launchers to have a shortcut. This is needed to make this feature
work reliably and should reduce the instances of "Meta key stopped working"
happening in general.
