serge-sans-paille bf3516e81e Bug 1964489 - Avoid duplication in NS_DECLARE_STATIC_IID_ACCESSOR / NS_DEFINE_STATIC_IID_ACCESSOR r=nika,necko-reviewers,media-playback-reviewers,places-reviewers,win-reviewers,dom-storage-reviewers,xpcom-reviewers,gstoll,janv,emilio,padenot,valentin,asuth
In modern C++, static constexpr member variables are automatically
inline (aka weak) so the template trick is not needed. This also avoid
duplication and reduces the amount of parsed code. No impact on
generated binary (actually: smaller debuginfo, close to identical
binary).
