Pinned Channels (#2811)

* Switch to pinned channels. * Fix ServerRenderer so it's not blocked until the result is resolved. * Fix tests. * Remove unused SendError. * Revert channel-based BufWriter. * Removed unused fmt module. * Update docs. * Add safety comments, adjust borrowing designs. * Adjust oneshot as well. * Fix workflow temporarily. * Cell or UnsafeCell? * Update safety notice. * Should be sync. * Actually should be both. * Update packages/yew/src/platform/pinned/mpsc.rs Co-authored-by: Muhammad Hamza <muhammadhamza1311@gmail.com> Co-authored-by: Muhammad Hamza <muhammadhamza1311@gmail.com>
