767: Stm32 fixes r=lulf a=jr-oss
Using embassy on STM32 Discovery board showed problems with
- USART with parity
- Clock settings (CFGR) when using PLL and prescaler
- Flash ACR settings
This PR attempts to fix these

PLL settings remained intact because these bits are not writable when PLL is enabled,
but prescaler settings were overwritten by selecting PLL as sysclk (CFGR.SW[1:0]).
765: Implement Output::is_set_low for embassy-rp r=Dirbaio a=danbev
This commit implements a suggestion for the method `is_set_low` which is
currently a `todo`, by reading last value written to `GPIO_OUT`.

751: Use explicit return statement TaskStorage::spawn r=Dirbaio a=danbev
This commit removes the else branch in `TaskStorage::spawn`, and returns
explicitly from the if statement's branch, similar to what
[TaskPool::spawn](85c0525e01/embassy/src/executor/raw/mod.rs (L235-L243)) does.

This commit removes the else branch in TaskStorage::spawn, and returns
explicitly from the if statement's branch, similar to what
TaskPool::spawn does.
The replacement is `embassy-usb`. There's a WIP driver for stm32 USBD in #709,
there's no WIP driver for stm32 USB_OTG. This means we're left without
USB_OTG support for now.
Reason for removing is I'm going to soon remove `embassy::io`, and
USB uses it. I don't want to spend time maintaining "dead" code
that is going to be removed. Volunteers welcome, either to update
old USB to the new IO, or write a USB_OTG driver fo the new USB.
749: Rename spawn_allocate to spawn_mark_used r=Dirbaio a=danbev
This commit contains a suggestion to rename `TaskStorage::spawn_allocate`.
The motivation for this is when reading through the code I was
expecting something else to happen in this method, due to `allocate` in
the method name.
I'm very new to this code base so I may be wrong in thinking this
is a good change, but I wanted to open this PR to get some feedback.
