Now that we have a system-wide page pool, we can use that for the live
frame mode of BPF_TEST_RUN (used by the XDP traffic generator), and
avoid the cost of creating a separate page pool instance for each
syscall invocation. See the individual patches for more details.

net: Register system page pool as an XDP memory model
bpf: test_run: Use system page pool for XDP live frame mode
bpf: test_run: Fix cacheline alignment of live XDP frame data
