This exists as a separate crate to work around cargo being unable to conditionally compile crate-types.
This leads to problems like emscripten being unable to link
because symbols like logjs are not defined even if the cratetype
is not actually desired. As a workaround, the icu_capi_staticlib and
icu_capi_cdylib crates exist as endpoints to be built when those
respective library types are needed.
