595: stm32f3: fix nonexistent cfg tests r=Dirbaio a=unrelentingtech

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 #580 too.

---

I don't have any F3 boards, so this is not tested. But the original cfg clearly doesn't look right…

482389a691 Own the sequence buffer
This approach owns the sequence buffers which, while introducing an extra move, it eliminates the need to guard the lifetime of the sequence buffer. Given ownership, the buffer will be retained until the PWM sequence task is stopped.

47aeab152f PWM WS2812B example and per sequence config
Demonstrates how to set the colour of a WS2812B to blue using PWM, and the use of multiple sequences along with their own config. This required an API change.

589: stm32/i2c: allow empty writes r=Dirbaio a=darkwater

The Senseair Sunrise CO2 sensor expects a wake-up packet in the form of (START, address, STOP), which looks like a `write(addr, &[])`, but this assertion prevents sending that.

I'm not sure why the assertion is there. Sending empty packets works fine in my limited testing, at least.

590: Stop PWM before assigning the new sequence r=huntc a=huntc

I had introduced a small bug in my last PR where I assigned the sequence before stopping the PWM. I now stop the PWM before doing that now.

Also, corrected a math comment.

585: Permit many sequences to be passed r=huntc a=huntc

Sequences are now passed in via the start method to avoid having to stop the PWM and restart it. Sequences continue to be constrained with the same lifetime of the Pwm struct itself. The pwm_sequence example has been extended to illustrate multiple sequences being passed around.

48afef28a0 Strengthen the borrow
The start method is now safe. Because it has the potential of borrowing the sequence and mutating itself, the sequence must outlive the Pwm struct.

586: stm32: add `time-driver-any` cargo feature that automatically picks one. r=Dirbaio a=Dirbaio

Most of the time you don't care which one gets used, so this is easier! :) 

It also helps for building docs for all chips, it reduces the feature changes needed.

581: stm32: expose all functionality as inherent methods. r=Dirbaio a=Dirbaio

This is the previous step to implementing both the embedded-hal 0.2 and embedded-hal 1.0 + embedded-hal-async traits.

The equivalent in nrf was done in #552 

- Removes need for `unwrap` in gpio.
- Removes need for `use embedded_hal::whatever` in all cases.

582: Make advanced timer trait not require general purpose timer trait as … r=Dirbaio a=matoushybl

…the timers are too different.

When developing pwm driver, I originally used T: GeneralPurpose16bitTimer as it could support both GP timers and advanced timer, but advanced timer requires further modifications in registers accessible only in it (BDTR - bit AOE).

This PR makes advanced timers depend on Basic16bitTimer instead, which should hopefully improve type safety and allow for better timer drivers that can distinguish between advanced timers and general purpose ones.
