88d07ef35b displayio: further ensure just one start_terminal call 
@cwalther determined that for boards with 2 displays (monster m4sk),
start_terminal would be called for each one, leaking supervisor heap
entries.

Determine, by comparing addresses, whether the display being acted on
is the first display (number zero) and do (or do not) call start_terminal.

stop_terminal can safely be called multiple times, so there's no need
to guard against calling it more than once.

Slight behavioral change: The terminal size would follow the displays[0]
size, not the displays[1] size

774f2e16ba displayio, framebufferio: Remove spurious call to supervisor_start_terminal 
A call to supervisor_start_terminal remained in
common_hal_displayio_display_construct and was copied to other display
_construct functions, even though it was also being done in
displayio_display_core_construct when that was factored out.

Originally, this was harmless, except it created an extra allocation.
When investigating #3482, I found that this bug became harmful,
especially for displays that were created in Python code, because it
caused a supervisor allocation to leak.

I believe that it is safe to merge #3482 after this PR is merged.

b1592564b2 displayio: Fix matrixportal crash 
An RGBMatrix has no bus and no bus_free method.  It is always possible
to refresh the display.

This was not a problem before, but the fix I suggested (#3449) added
a call to core_bus_free when a FramebufferDisplay was being refreshed.
This was not caught during testing.

This is a band-aid fix and it brings to light a second problem in which
a SharpDisplay + FrameBuffer will not have a 'bus' object, and yet does
operate using a shared SPI bus.  This kind of display will need a
"bus-free" like function to be added, or it can have problems like
#3309.

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