Setup the qemuboot variables and qemu-xilinx-helper-native environment
to use the multiarch script to start a QEMU multiarch instance with the
MicroBlaze PMU.

This change reworks how the meta-xilinx layer enables and provides the
custom version of QEMU based on Xilinx's fork of QEMU. The existing
implementation relied on the single sysroot which was changed in oe-core
such that now recipes have their own sysroots (RSS support).
Additionally oe-core now provides the QEMU binaries to the runqemu
script via the 'qemu-helper-native' recipes sysroot as opposed to the
image sysroot.
These rework changes allow for a single machine to select the targeted
QEMU version as well as to provide the qemuboot config specific to the
targeted QEMU version. The selection of QEMU version is now handled by
PREFERRED_PROVIDER mechanics with the meta-xilinx layer providing an
additional recipe that is equivalent to qemu-helper-native and which
also provides said target allowing for the machine to select via the use
of PREFERRED_PROVIDER_qemu-helper-native. This recipe
(qemu-xilinx-helper-native) however instead provides the sysroot
populated with qemu-xilinx instead of qemu.
Additionally the XILINX_QEMUBOOT variable is replaced with the
qemuboot-xilinx.bbclass, this provides the overrides for setting up
qemu-xilinx specific QB_* args. Additionally this bbclass points runqemu
at the qemu-xilinx-helper-native sysroot for QEMU binaries.
These changes also work towards making the meta-xilinx layer better
handle multiple qemuboot.conf variants as well as handling different
QEMU versions.
This change also removes the 'qemu-system-xilinx' MACHINE_FEATURES, this
is due to MACHINE_FEATURES no longer being available for native recipes.
Additionally there is no longer any logic that needs to know this any
way.

Avoid using the MACHINE_DEVICETREE variable for detection of the device
tree that needs to be loaded. Instead only rely on IMAGE_BOOT_FILES or
KERNEL_DEVICETREE.

Currently the mainline QEMU is lacking full support for emulating the
ZCU102 board. So use the more functional Xilinx QEMU for this board.
Also reformat some of the appends to QB_* variables for clarity.

Move the common setup for QEMU machines into an include call
'machine-xilinx-qemu.inc'. This include is added to any machine that has
a QEMU model. It sets up common QB_* values as well as inheriting the
qemuboot class and adding the EXTRA_IMAGEDEPENDS on qemu-native.
This include also has helper functions to automatically determine the
DTB from KERNEL_DEVICETREE/MACHINE_DEVICETREE and automatically setup the
'console=' kernel command line based on SERIAL_CONSOLE.
