plasma-desktop: add missing gsettings schemas on kaccess

this commit lets kaccess to read screen reader settings[1] using
gsettings by adding required gsettings schemas dirs to the $XDG_DATA_DIRS

this commit also refactors previus gsettings schemas fix of kcm_access
for allowing reuse of wrapped gsettings between kaccess and kcm_access
