This patch:
1. Adds setup scripting to "provision_root.sh" to setup and enable KVM,
for the 'vagrant' user, for VMs which are capable of this.
2. Runs a check on each VM to see if KVM can be run sucessfully within a
docker container. If so, the GitHub Actions runner is given a 'kvm'
label. It is unknown at this time if GitHub Runners can utlized KVM
but it is open to their processes.

THe `lvextend` command extends the logical volume. However, the
`resize2fs` command is needed to extend the filesystem to fill the
logical volume.
Prior to this patch the filesystem ran out of space despite there being
enough room in the volume. This was just wasted free space.
Prior to this change we were limited to a root partition with only 60GB
of space which caused issues when running larger simulations (see:
https://github.com/gem5/gem5/issues/165).
There are two factors in this issue which this patch resolves:
1. The root partition in the VM was capped at 60GB despite the virtual
machines size being capped at 128GB. This resulted in libvirt giving the
VM free space it couldn't use. To fix this `lvextend` was added to the
"provision_root.sh" script to resize the root partition to fill the
available space.
2. The virtual machine size can be set via the `machine_virtual_size`
parameter. The minimum and default value is 128GB. This wasn't exposed
previously. Now, if we required, we can increase the size of the VM/Root
partition if we require (though I believe 128GB is more than sufficient
for now).
