Merge #784

784: stm32: make tick rate configurable r=Dirbaio a=willglynn

The stm32 time drivers support arbitrary tick rates but the associated Cargo features do not. Enabling any time driver presently enables `embassy/time-tick-32768hz`; instead, enable only `embassy/time`.

Additionally, `embassy/time` now functions in the absence of any `embassy/time-tick-*` feature, defaulting to 32768 Hz if left unspecified.
