Move HSE config out of main clock mux 
This makes the configuration more flexible and closer to the underlying
configuration register structure. For example, we could use HSI for the
system clock, but use HSE to output a clock with MCO.

484e0acc63 Add stm32 flash + bootloader support 
* Add flash drivers for L0, L1, L4, WB and WL. Not tested for WB, but
should be similar to WL.
* Add embassy-boot-stm32 for bootloading on STM32.
* Add flash examples and bootloader examples
* Update stm32-data

Merge #714 
714: add more clock options for l4 and l5 r=Dirbaio a=ant32

- added an assert so it panics if pll48div is not 48Mhz
- added MSI as a clock source for PLL
- removed hsi48 option for MCUs mentioned in l4 rcc presentation
- copied some code from l4 to l5, but don't have a way of testing it.

047ff9a2f2 Use new stm32-data registers and fix AHB clock calculation 
The original code for calculating the AHB clock did not account for the gap in
prescaler values (32 is not an available value.) The bit shifting and math has
been replaced by a `match`.

8bb41a3281 stm32f3: fix nonexistent cfg tests 
The rcc code was taken from stm32-rs which uses 'x' features, but
embassy uses features with full chip names.

Add these 'x' wildcards as cfgs and use them in rcc.
They will be useful for USB too.

540: Initial support for STM32F3 r=Dirbaio a=VasanthakumarV

The [companion PR](https://github.com/embassy-rs/stm32-data/pull/109) in `stm32-data` should be merged before this PR.
The examples were tested on an STM32F303VC MCU.

Merge #482 
482: Add MCO peripheral. r=Dirbaio a=matoushybl

This PR adds an abstraction over STM32 RCC feature called MCO (Microcontroller Clock Output). The clock output can bind to several clock sources and then can be scaled using a prescaler.

Given that from the embassy ecosystem the RCC is generaly invisible to the user, the MCO was implemented as a separate peripheral bound to the pin where the clock should appear.

7ad6280e65 Add HAL for SubGhz peripheral for STM32 WL series 
Based on the HAL from stm32wl, the peripheral driver has been
modified to fit into embassy, using the embassy APIs, providing
operation of the radio peripheral.

The initial version does not offer any async APIs, but the example
shows how the radio IRQ can be used to perform async TX of the radio.
