3c083330f8 RGBMatrix: Remove unused, dead allocation 
@tannewt noticed this in a pull request review.  The allocated
memory was never used, but the GC would have collected it eventually.

71c63c2812 FramebufferDisplay: Don't set rotation via core_construct 
The expectations of displayio.Display and frambufferio.FramebufferDisplay
are different when it comes to rotation.

In displayio.Display, if you call core_construct with a WxH = 64x32
and rotation=90, you get something that is 32 pixels wide and 64 pixels
tall in the LCD's coordinate system.

This is fine, as the existing definitions were written to work like this.
With framebuffer displays, however, the underlying framebuffer (such as
RGBMatrix) says "I am WxH pixels wide in my coordinate system" and the
constructor is given a rotation; when the rotation indicates a transpose
that means "exchange rows and columns, so that to the Groups displayed
on it, there is an effectively HxW pixel region for use".

Happily, we already have a set_rotation method.  Thus (modulo the time
spent debugging things anyway:) the fix is simple: Always request no
rotation from core_construct, then immediately fix up the rotation
to match what was requested.

Testing performed: 32x16 RGBMatrix on Metro M4 Express (but using
the Airlift firmware, as this is the configuration the error was reported
on):
 * initially construct display at 0, 90, 180, 270 degrees
 * later change angle to 0, 90, 180, 270 degrees
 * no garbled display
 * no safe mode crashes

2f120c70ee rgbmatrix: recover gracefully from allocation errors 
e.g., allocating a 192x32x6bpp matrix would be enough to trigger this
reliably on a Metro M4 Express using the "memory hogging" layout.
Allocating 64x32x6bpp could trigger it, but somewhat unreliably.

There are several things going on here:
 * we make the failing call with interrupts off
 * we were throwing an exception with interrupts off
 * protomatter failed badly in _PM_free when it was partially-initialized

Incorporate the fix from protomatter, switch to a non-throwing malloc
variant, and ensure that interrupts get turned back on.

This decreases the quality of the MemoryError (it cannot report the size
of the failed allocation) but allows CircuitPython to survive, rather
than faulting.

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