Cherry-pick ICU-21448: Update Android ICU tzdata
from 2020d to 2020f. [O-MR1 CTS]

This is a cherry pick of
https://github.com/unicode-org/icu/commit/25eb1510ec4e536fe0d0d1024b3ce71819510d0a.

New test cases in SimpleDateFormat.java and tzfmttst.cpp
were skipped as they rely on prod code changes. See
https://github.com/unicode-org/icu/pull/1526/files#r552372640
for more details.

For CTS, code and data changes were skipped from original CL as goal
is to fix failing TimeZoneTest on devices with 2020f update.

See b/177644925 for partner reported waiver req.
