c501b162fc Enable clock by default for stm32l0 
Modify init function to return a Clock instance defined by a per-chip
SystemClock type and use this in macro setup

A proof of concept implementation for STM32 L0 chips.

This allows using embassy::main macros for STM32 devices that have the
clock setup logic.

1c10e746b6 Re-adds embassy macros for stm32 
* Hook RCC config into chip config and use chip-specific RCC init
  function
* RTC/clock setup is ignored for now

dc67d2f4a4 impl Unborrow for &'a mut T 
This plays nicer with user code that's generic over peripheral traits like `Instance` or `Pin`.

9586365b07 Pass config directly to chip specific configure function 
This removes the need to duplicate the configuration for each individual
chip, but will instead pass on the configuration specified in the config
attribute.

Update nrf, stm32, rp macros with passing the config to a per-chip
configure function which assumes the appropriate configuration to be
passed to it.

To demonstrate this feature, the stm32l0xx clock setup and RTC is added which exposes
clock configuration different from stm32f4xx (and has a different set of timers and HAL APIs).

37b3d8b22c Add embassy_prefix attribute parameter to task and main macros 
This allows crates depending on embassy that wants to use a different
module path to do so for the 'task' and 'main' macros, by passing the
parameter 'embassy_prefix'. The prefix defaults to '::', which will
retain the existing behavior.

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.
