ICE-6481 pragma comment when building static libraries

On windows with VS, pragma comment is now defined when building only when
ICE_BUILDING_<component-name> is not defined. ICE_BUILDING_<component-name>
is defined automatically when <component-name>_API_EXPORTS is defined. When building
static Ice libraries on Windows, please define
ICE_BUILDING_<component-name-being-built>.

ICE_DECLSPEC_EXPORT and ICE_DECLSPEC_IMPORT are now defined all the time on Windows,
and we define the various _API macros to /**/ when ICE_STATIC_LIBS is defined.

Replaced various direct use of ICE_DECLSPEC_EXPORT/ICE_DECLSPEC_IMPORT by
the correct _API macro.
