Peter Maydell f7214f99ff vl.c: Remove pxa2xx-specific -portrait and -rotate options
The ``-portrait`` and ``-rotate`` options were documented as only
working with the PXA LCD device, and all the machine types using
that display device were removed in 9.2.

These options were intended to simulate a mobile device being
rotated by the user, and had three effects:
 * the display output was rotated by 90, 180 or 270 degrees
   (implemented in the PXA display device models)
 * the mouse/trackpad input was rotated the opposite way
   (implemented in generic code)
 * the machine model would signal to the guest about its
   orientation
   (implemented by e.g. the spitz machine model)

Of these three things, the input-rotation was coded without being
restricted to boards which supported the full set of device-rotation
handling, so in theory the options were usable on other machine
models with odd effects (rotating input but not display output).  But
this was never intended or documented behaviour, so we can reasonably
drop these command line arguments without a formal deprecate-and-drop
cycle for them.

Remove the options, and their implementation and documentation.
Describe the removal in removed-features.rst.
