Fix loading app-local ICU

[tarekgh]

#77045

Awhile ago we had a change #68847 to fix the build breaks because of obsoleted ICU APIs. The fix was changing static binding to the API during the compile time to be a runtime binding. This change work fine except we missed to do some pointer initialization when having app-local ICU .
