Give users the option to configure SYST with an external clock source.
By default, the clock source is the core, which keeps us backwards
compatible.
`_start` has a new input, but since users don't call that function
directly, it doesn't seem like a problem to break that public API.
This doesn't fix the GPIO interrupt triggering during a higher priority
CPU task, but does fix rtic-monotonics. I am unsure how to fix the
former as PLIC_MX doesn't have a function like `cpu_intr_from_cpu_x` to
pend/unpend CPU interrupts, and if the CPU interrupts are enabled with
PLIC_MX instead of INTPRI then the MCU just hangs when there is a CPU
interrupt.
* Fix stm32 read-modify-write problem
The `SR` register for STM32 clears when writing a zero to a bit.
Therefore, all registers that should not be cleared need to be `1`.
`modify` here caused a read-modify-write error that could clear
unrelated flags.

* Rework timer_queue and monotonic architecture
Goals:
* make Monotonic purely internal
* make Monotonic purely tick passed, no fugit involved
* create a wrapper struct in the user's code via a macro that then
converts the "now" from the tick based monotonic to a fugit based
timestamp
We need to proxy the delay functions of the timer queue anyway,
so we could simply perform the conversion in those proxy functions.
