hw/display/apple-gfx: Adds configurable mode list

This change adds a property 'display_modes' on the graphics device
which permits specifying a list of display modes. (screen resolution
and refresh rate)

The property is an array of a custom type to make the syntax slightly
less awkward to use, for example:

-device '{"driver":"apple-gfx-pci", "display-modes":["1920x1080@60", "3840x2160@60"]}'

hw/display/apple-gfx: Introduce ParavirtualizedGraphics.Framework support

MacOS provides a framework (library) that allows any vmm to implement a
paravirtualized 3d graphics passthrough to the host metal stack called
ParavirtualizedGraphics.Framework (PVG). The library abstracts away
almost every aspect of the paravirtualized device model and only provides
and receives callbacks on MMIO access as well as to share memory address
space between the VM and PVG.

This patch implements a QEMU device that drives PVG for the VMApple
variant of it.

Subsequent changes:

* Cherry-pick/rebase conflict fixes, API use updates.
* Moved from hw/vmapple/ (useful outside that machine type)
* Overhaul of threading model, many thread safety improvements.
* Asynchronous rendering.
* Memory and object lifetime fixes.
* Refactoring to split generic and (vmapple) MMIO variant specific
code.

Implementation wise, most of the complexity lies in the differing threading
models of ParavirtualizedGraphics.framework, which uses libdispatch and
internal locks, versus QEMU, which heavily uses the BQL, especially during
memory-mapped device I/O. Great care has therefore been taken to prevent
deadlocks by never calling into PVG methods while holding the BQL, and
similarly never acquiring the BQL in a callback from PVG. Different strategies
have been used (libdispatch, blocking and non-blocking BHs, RCU, etc.)
depending on the specific requirements at each framework entry and exit point.
