Roll icu to 241739 and drop a version from icudt*dat

Roll icu to 241739 and drop a version from icudt*dat

For details on icu@r=241739, see
      https://codereview.chromium.org/111723007/ and
      https://codereview.chromium.org/118373006/
    They're the ICU-side of changes to enable icu_use_data_file.


In addition, icudt46l.dat is renamed icudtl.dat (no version number)
so that icu_util.cc has to be changed.

This CL should be no-op except on iOS [1]  until 3 platform specific CLs listed below
are landed after this CL gets landed.
  Windows (https://codereview.chromium.org/99473012 ),
  Linux ( https://codereview.chromium.org/102413007 )
  Mac ( https://codereview.chromium.org/109013004 )

[1] iOS currently has icu_use_data_file_flag=1 and the change in icu.gyp affects iOS builds.  

BUG=72633
TEST=All builds on all platforms go through and tests using icu data
(e.g. layout tests, base_unittests:*String*, net_unittests:*IDN* ) pass.

This is to roll ICU to enable icu_use_data_file. I also moved the change in
icu_util.cc to deal with the icudt*dat name change  out of the Mac CL (
https://codereview.chromium.org/109013004 ). 

Can you approve? Thanks.

ios_dbg_simulator does not seem to like icu.gyp changes. {ui,base,net}_unittests
failed to find icudtl.dat in bundle. (more details at
https://codereview.chromium.org/111723007/ )  I'm trying ios_rel_devices.
