1371: RTC r=Dirbaio a=xoviat
This adds RTC for most of the stm32 chips. Nearly all of the work was not done by me, but I took it the last bit by disabling the chips that weren't working. I think it would be easier to enable them in future PRs if requested.

1360: stm32/rcc: add i2s pll on some f4 micros r=Dirbaio a=xoviat
Adds the i2s pll on some f4 micros.
1361: Executor: Replace unnecessary atomics in runqueue r=Dirbaio a=GrantM11235
Only the head pointer needs to be atomic. The `RunQueueItem` pointers are only loaded and stored, and never concurrently

1330: stm32/pwm: add complementary pwm r=Dirbaio a=xoviat
This implements complementary PWM with dead time on many supported targets. The specific dead-time programming functions are passed through directly to the user, which is a bit ugly but the best compromise I could reach for now.

The internal channels (vbat, vref, and temperature) are not real pins and do
not have the `set_as_analog` method. They must be read using the
`read_internal` method.
