boards/qemu-intel64: add python configuration
Add a defconfig that runs CPython on qemu-intel64 (flat build) and
place the .PyRuntime section (created by the apps CPython port) in
.data so it is covered by the kernel physical mapping.

The "standard" NuttX examples/ostest configuration with
the default console on legacy UART0 port (base=0x3f8)
+python
+------
+
+This configuration runs the CPython interpreter (``apps/interpreters/python``)
+with SMP and networking (e1000) enabled. It works only with the Make-based
+build system.
+
+Command to run the image with user-mode networking::
+
+ qemu-system-x86_64 -m 2G -smp 4 -cpu host -enable-kvm \
+ -kernel nuttx -nographic -serial mon:stdio \
+ -device e1000,netdev=u0 -netdev user,id=u0
+
+Then start the interpreter from NSH::
+
+ nsh> python
