Deprecate KVM support for AArch32pull-target-arm-20200414
The Linux kernel has dropped support for allowing 32-bit Arm systems to host KVM guests (kernel commit 541ad0150ca4aa663a2, which just landed upstream in the 5.7 merge window). Mark QEMU's support for this configuration as deprecated, so that we can delete that support code in 5.2.

+its support for this configuration and will remove it in a future version.
+Running 32-bit guests on a 64-bit Arm host remains supported.
