Move startup_helper_win.cc to separate target for incremental build

Currently, the .cc is included in multiple targets. In incremental builds this results in errors like:

[609->8104/8713 ~0] LINK_EMBED unit_tests.exe

when incremental_chrome_dll=1 used in Release build.

By putting the .cc in a static_library target and depending on it as necessary, rather than including the .cc into multiple places, this is avoided.
