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). Differential Revision: https://phabricator.services.mozilla.com/D247825
