mac: change display name retrieval to localizedName NSScreen property

the old displayName property via the IODisplay API is not working
anymore on ARM based macs and was broken in at least one other case.

instead we use the new localizedName property introduced in 10.15 of the
NSScreen. we don't need any backwards compatibility since 10.15 is the
oldest version we support now.

configs and scripts that use the options and properties fs-screen-name,
screen-name or display-names need to be adjusted since the names could
differ from the previous implementation via the IODisplay API.

Fixes #9697
