Switch to pin, frequency and duty_cycle PulseOut
Passing in a PWMOut still works but is deprecated. It will be
removed in CircuitPython 8.0.0

This also switches STM32 timer indices and channel indices to
0-based in our pin data rather than `- 1` everywhere. The latter is
more bug prone.

Most of the way for #3264

Tested on Metro M0, Metro M4, Feather S2, Feather nRF52840, Feather
STM32F4 and Arduino RP2040.

Also found a race condition between timer_disable and redraw, which
would happen if I debugger-paused inside common_hal_rgbmatrix_timer_disable
or put a delay or print inside it.  That's what pausing inside reconstruct
fixes.

So that the "right timer" can be chosen, `timer_allocate` now gets the `self`
pointer.  It's guaranteed at this point that the pin information is accurate,
so you can e.g., find a PWM unit related to the pins themselves.
This required touching each port to add the parameter even though it's
unused everywhere but raspberrypi.

Split pulseio.PWMOut into pwmio
This gives us better granularity when implementing new ports because
PWMOut is commonly implemented before PulseIn and PulseOut.

Fixes #3211
