[edk2-devel] [PATCH v3] Revert "OvmfPkg: Update build.sh to allow building OVMF then running QEMU"

["Mike Beaton" <mjsbeaton@gmail.com>]

This reverts commit 173a7a7daaad560cd69e1000faca1d2b91774c46

Fixes https://bugzilla.tianocore.org/show_bug.cgi?id=4528

The build.sh qemu option starts the correct qemu executable for the selected
architecture (build.sh -a option, or implicit) and uses the correct previously
built OVMF image for the selected architecture and build target (build.sh -b
option, or implicit).

With this revert, the above step will fail if there is no matching previously
built OVMF image. This is advantageous over rebuilding each time the build.sh
qemu option is used (as in the reverted commit), because it provides a quick
way to run a just-built OVMF image in place, while:
 a) Starting immediately (saving the time required for a rebuild on each
    usage, if the VM is started multiple times)
 b) Preserving the NVRAM contents between multiple runs (i.e. until the
    image is next rebuilt)
