  1. pillar: Adapt pillar to use native cpupinning 

    Update pillar's handling of QEMU guests to take advantage of native CPU pinning
options introduced in the newer version of QEMU (8.0.4). This eliminates the need
for our custom patches to QEMU for CPU pinning. The following changes are included:
Removing custom qemu cpu-pinning patches to include the native qemu-pinning feature (1)
Refactoring CPU pinning to use integer slices instead of comma-separated strings (2)
Updating QEMU command-line arguments to include native CPU pinning options (3)
Ensuring compatibility with both KVM and Xen hypervisors (4)

This change allows us to leverage upstream QEMU improvements and simplifies
the codebase by removing custom patches and complex string manipulations. Tested with QEMU version 8.0.4
