A new `split` method is introduced such that the Uarte tx and rx can be used from separate tasks. An MPSC is used to illustrate how data may be passed between these tasks.

531: Rust Analyzer documentation r=Dirbaio a=huntc
Intends to clarify how to make Embassy usable from within Visual Studio Code by assuming the presence of the Rust Analyzer.
Note that IntelliJ does not support the Rust Analyzer, so an open question remains as to the whether this is a good move. If it turns out not to be a good move then we should still look at clarifying the use of a workspace file.

`async fn`s do nothing until polled, but we want the DMA transfer to
immediately start in this case. Drivers rely on it. Some require special
orders, such as "start DMA, start SPI, then wait for DMA" which is awkward
to do without eager start.
Also use a manually-impl'd future, this allows getting rid of the "double"
Unborrow channel clone.
