This rewrite simplifies the channel implementation considerably, with 34% fewer LOC. Perhaps the most important change is the removal of the channel state, which made sense when we had only send and receive operations but only makes things more compliated when multiple select operations can be pending on a single channel.
I did this rewrite originally to make it possible to make channels parallelism-safe (see https://github.com/tinygo-org/tinygo/issues/2446). The current implementation is not parallelism-safe, but it will be easy to make it so (the main additions will be a channel lock, a global select lock, and an atomic compare-and-swap in chanQueue.pop).
This change also reduces binary size: for the driver examples that do change (presumably the ones that use a channel), the code size is reduced by around 400 bytes.
