da91779117 interrupt: Split set_handler context. 
Since introducing the ctx pointer, the handler is now two words, so setting it can
race with the interrupt firing. On race it's possible for the new handler to be
alled with the old ctx pointer or viceversa.

Rather than documenting this, it's better to split the function in two to make it
obvious to the user that it's not atomic. The user can use a critical section, or
disable/enable the interrupt to avoid races if this is a concern.

11be9170ec Cleanup interrupt package naming. Fixes #40 
The `interrupt` package previously tried to be drop-in compatible with the
`interrupt` package from PACs. THis meant that there was both a PAC-style enum
value `UARTE0` and an embassy-style owned `UARTE0Interrupt` type. This made
things VERY confusing.

This drops compatibility with the PAC, improving the names for embassy interrupts.

93780fa31d uarte: Wait for the peripheral to be disabled

2. Free Uarte::free()

85ec9dd16f uarte: Be on safe side with potentially racy code 
The PS does not specify how many cycles it takes for a STARTXX task to
generate a XXSTARTED event. I think it is instantaneous but let’s be on
the safe side for the following sequence:
1. poll() starttx
2. drop() txstarted not yet set, but future gets dropped
3. txstarted set by hardware, peripheral enabled after it was dropped

a3b3305b8e uarte: Only stop TX forcefully when a transmissions is running 
This comes with insignificant power consumption improvements but makes
the code of the RX and TX case symmetric.

Timo Kröger
a7c03e4cb6 uarte: Only stop RX forcefully when a reception is running 
The STOPRX task always triggers a timeout of ~55bit times until the
RXTO event is generated. Before we disabled the receiver only after
the timeout.
With this change the receiver is stopped right after reception has ended
because the DMA buffer is full.
For forced RX aborts like `stop()` or on drop still need to wait for the
RXTO event before disabling the receiver.

Timo Kröger
9f28c7ab8d uarte: Do not spin when stopping a receive future 
Spinning on drop() is still required when the future has not been
stopped so that DMA finishes before the buffer is released.
