ICU resources: update resources to version 60b.

The resources were copied from the Android Pie release:
https://android.googlesource.com/platform/external/icu/+/refs/heads/pie-release/icu4j/main/shared/data/

Also a few files were updated to their Pie version to fix runtime/test errors caused by this update:
+ Normalizer2Impl.java: tied to a new version of the embedded data (see isDataVersionAcceptable method).
+ Norm2AllModes.java: updated due to changes in Normalizer2Impl API.
+ DateTimePatternGenerator.java: to support the new datetime formats:b and B.
