Remove synthetic_alias list in data/*/reslocal.mk

reslocal.mk files have a line 'FOO_SYNTHETIC_ALIAS' with in_ID, iw_IL, no_NO,
but we don't include the corresponding targets (id_ID, he_IL and nb_NO).
For now, make FOO_SYNTHETIC_ALIAS empty because we don't have a strong
need to include id_ID, he_IL and nb_NO.

This issue was found while building icudt DLL file on Windows. Linux/Mac
didn't complain, though.

This CL updates icudt assembly files for Linux/Mac with the above change
and adds icudt46l.dat and pre-built icudt46.dll for Windows.

BUG=61514
TEST=icudt_build runs fine on Windows with CL 6460007 patched in.
