Add static library versions of libdawn*
Chromium will want to have both static and shared library versions of Dawn to use in non-component and component builds respectively. The *_export.h files are modified to noop when *_SHARED_LIBRARY is not defined so that the static library doesn't export symbols that aren't imported in dependents (this would break compilation on Windows). A dawn_library_combo is introduced in BUILD.gn that factors out all the logic needed to produce shared libraries and handle the _EXPORT macros. Also contains a fix to dawncpp to export only the methods that aren't defined in the header (otherwise they get defined multiple times) BUG=dawn:85 Change-Id: Ib747deb9308e1165dd66002487147ba279d3eac0 Reviewed-on: https://dawn-review.googlesource.com/c/3761 Reviewed-by: Corentin Wallez <cwallez@chromium.org> Commit-Queue: Corentin Wallez <cwallez@chromium.org>
