[KRunner] Make KRunner width configurable
This is part of a series of MRs to add configurable width in KRunner.
The MR in frameworks/krunner is not necessary anymore: frameworks/krunner!105 (closed)
- First a runnerWidth property/getter/signal is added to View in plasma-workspace and the property is used via runnerWindow to set width in plasma-workspace plasma-workspace!1936 (closed)
- then it can be configured via the GUI in plasma-desktop (this MR !1053 (closed) )
