[PATCH v3 3/6] nativesdk-packagegroup-sdk-host: gate qemu behind SDK_FEATURES

[Trevor Woerner <twoerner@gmail.com>]

qemu (with its helper) is added to every standalone SDK on the
architectures where it builds. It is only useful for running target
binaries on the host via qemu-usermode, which not every SDK user wants,
and it is a large thing to carry when they do not.

Move it behind the "qemu" SDK feature, which is enabled by default so an
unmodified configuration still gets qemu exactly as before on the same
architectures; the architecture guard is retained. A configuration that
does not want it removes the "qemu" feature from SDK_FEATURES.
