forgot to remove these when they were no longer necessary or useful. oops.

1376: rtc: cleanup and consolidate r=Dirbaio a=xoviat
This removes an extra file that I left in, adds an example, and consolidates the files into one 'v2' file.

this reports errors at the same location the blocking uart would, which
works out to being mostly exact (except in the case of overruns, where
one extra character is dropped). this is actually easier than going
nuclear in the case of errors and nuking both the buffer contents and
the rx fifo, both of which are things we'd have to do in addition to
what's added here, and neither are needed for correctness.
the rp uart receive fifo is 32 entries deep, so the 31 byte test data
fits into it without needing any buffering. extend to 48 bytes to fill
the entire fifo and the 16 byte test buffer.
rp-hal has done this very well already, so we'll just copy their entire
impl again. only div.rs needed some massaging because our sio access
works a little differently, everything else worked as is.
1321: executor: add Pender, rework Cargo features. r=Dirbaio a=Dirbaio
This introduces a `Pender` struct with enum cases for thread-mode, interrupt-mode and
custom callback executors. This avoids calls through function pointers when using only
the thread or interrupt executors. Faster, and friendlier to `cargo-call-stack`.
`embassy-executor` now has `arch-xxx` Cargo features to select the arch and to enable
the builtin executors (thread and interrupt).
