572: Makes the uarte endtx event available r=Dirbaio a=huntc

This PR allows `event_endtx` to be used outside of the `Uarte` itself. As a consequence, PPI can be used to drive tasks given the end of transmission on the Uarte. This is particularly useful for situations like RS485 where a GPIO may be required to be set to high when transmitting, then cleared when done. A non-PPI approach can cause a delay in the clearing of this GPIO as other Embassy tasks might become scheduled. Not clearing the GPIO in a timely manner can be problematic.

Here's an example of our usage with this change:

```rust
    let uarte_tx_enable = OutputChannel::new(
        p.gpiote_ch,
        Output::new(p.uarte_tx_enable_pin, Level::Low, OutputDrive::Standard),
        OutputChannelPolarity::Set,
    );

    let mut ppi = Ppi::new_one_to_one(p.ppi_ch, uarte.event_endtx(), uarte_tx_enable.task_clr());
    ppi.enable();
```

...and then later when writing:

```rust
    uarte_tx_enable.set();
    let _ = uarte_tx.write(&datagram_buf).await;
```

567: Remove unsafe from new on RND r=Dirbaio a=huntc

Unsafe is not required here given that all futures are required to live longer than their global peripheral instances. There are other occurrences of unsafe being used on new that should be removed. I started to do that but then went down a bit of a rabbit hole. Therefore, just confining this PR to what I'm currently exposed to.

563: Initial ADC support for on STM32F1xx  r=Dirbaio a=sjoerdsimons

Add an ADC implementation for F1 based chips. Primarily tested using ADC1, proper functionality for ADC2 probably needs some extra work as it's mainly a slave and can't e.g. measure vrefint by itself.

#526 seems to suggest that it will be rewritten for DMA support, but I am not sure how to implement it and the port was quite straightforward, so here it is. It might be immediately useful before DMA version will be implemented

Note that I have not tested this on v2 hardware
