Even though constexpr implicitly makes functions inline, we try not to rely on this implicit effect in the code base. We are mostly consistent about using `inline` on non-template free-functions to make it clear that we don't have an ODR violation. This patch simply fixes a few places where we didn't explicitly use inline on non-template free functions, presumably because they were constexpr. Fixes #75227
