Fix Wine locale picker values and labels

[ribbit384]

• moves the Wine locale picker source out of arrays.xml and into Kotlin via WineLocaleUtils
• replaces raw locale codes in the picker with explicit display labels while still saving normalized LC_ALL values
• normalizes LC_ALL when loading, saving, and launching containers/shortcuts so values like de_DE become de_DE.UTF-8
• updates both container settings and shortcut settings to share the same locale option source
• removes the old some_lc_all XML array
• intended impact: avoid crashes or bad runtime behavior from malformed Wine locale values and make the picker clearer
• validation: code review only; local Gradle/build checks were not run because java / JAVA_HOME is not configured on this machine
