Update IANA timezone db to 2019c

https://mm.icann.org/pipermail/tz-announce/2019-September/000057.html
     Fiji observes DST from 2019-11-10 to 2020-01-12.
     Norfolk Island starts observing Australian-style DST.

The tz-related files are updated by running update_tz.sh and ICU
data files are rebuilt.

Either in JS console in Chrome or v8 should work like these:
d8> new Date(Date.UTC(2019, 10, 8, 12)).toLocaleString("en", {timeZone: "Pacific/Fiji", timeZoneName: "long"})
d8> new Date(Date.UTC(2020, 0, 12, 12)).toLocaleString("en", {timeZone: "Pacific/Fiji", timeZoneName: "long"})

EXPECT to see these dates are under Standard Time.
"11/9/2019, 12:00:00 AM Fiji Standard Time"
"1/13/2020, 12:00:00 AM Fiji Standard Time"

BEFORE this CL we got them under Summer Time.
"11/9/2019, 1:00:00 AM Fiji Summer Time"
"1/13/2020, 1:00:00 AM Fiji Summer Time"
