Add the solution file for icu build on Windows

This will not be used in a regular Chromium/Blink build, but will
only be used to generate icudt.dll (pre-built icu dll file) from
icudtl.dat. 

Note that icudt.dll is not used in the default build configuration (with icu_use_data_file_flag=1) but GN build still uses it.
