Somehow the auto rolling of ICU does not happen after 2020/3/24
(see https://bugs.chromium.org/p/v8/issues/detail?id=10481) so I hand roll
ICU now.

For example, the following icu hash into chrome/src/DEPS was not yet
auto rolled after ~4 weeks:
2020/4/1 https://chromium-review.googlesource.com/c/chromium/src/+/2109133
2020/4/28 https://chromium-review.googlesource.com/c/chromium/src/+/2162266
