Chris Peterson b1f54173e8 Bug 1624776 - Replace MOZ_MUST_USE with [[nodiscard]] in xpcom. r=xpcom-reviewers,KrisWright
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.

Also remove MOZ_MUST_USE from nsIMemoryReporter's function pointer typedefs. [[nodiscard]] is an attribute of a function's declaration, not the function's type, and thus can't be applied to function pointers or lambdas.
