Also move MOZ_MUST_USE before function declarations' specifiers and return type. While clang and gcc's __attribute__((warn_unused_result)) can appear before, between, or after function specifiers and return types, the [[nodiscard]] attribute must precede the function specifiers.

I will admit from the start that this patch is goofy and is not the "proper" fix.
If you're unlucky enough to tickle the current unification in `dom/media`, then there's a conflict between `namespace mozilla::details` of `SPSCQueue.h` and `namespace details` of Chromium's `task.h`. Ultimately, the badness stems from some unified file doing `using namespace mozilla;`, but I'm really not enthusiastic about reworking that when I just want to get unblocked.
I'm going to attempt to justify the yuckiness of this patch on the basis that:
* `SPSCQueue.h` is super self-contained and rarely looked at, I bet nobody will notice this change
* Tons of other code prefers the spelling `mozilla::detail` anyway
