app/dma-perf: introduce dma-perf application

There are many high-performance DMA devices supported in DPDK now, and
these DMA devices can also be integrated into other modules of DPDK as
accelerators, such as Vhost. Before integrating DMA into applications,
developers need to know the performance of these DMA devices in various
scenarios and the performance of CPUs in the same scenario, such as
different buffer lengths. Only in this way can we know the target
performance of the application accelerated by using them. This patch
introduces a high-performance testing tool, which supports comparing the
performance of CPU and DMA in different scenarios automatically with a
pre-set config file. Memory Copy performance test are supported for now.
