net/memif: add a Rx fast path

For memif non-zero-copy mode, there is a branch to compare
the mbuf and memif buffer size during memory copying. Mbuf
and memif buffer size is defined at compile time. If memif
buf size <= mbuf size, add a fast Rx memory copy path by
removing this branch and mbuf bulk alloc.

The removal of the branch and bulk alloc lead to considerable
performance uplift.

Test with 1p1q on N1SDP AArch64 server,
--------------------------------------------
buf size | memif <= mbuf | memif > mbuf |
--------------------------------------------
non-zc gain | 26.85% | -0.37% |
--------------------------------------------
zc gain | 8.57% | 3.04% |

build: remove redundant _GNU_SOURCE definitions

The feature macro _GNU_SOURCE is defined globally,
but there was some remaining useless settings.

The internal definition in config/meson.build is kept,
all other internal definitions of _GNU_SOURCE are removed,
except in examples, which can be built as external applications.
Note: external applications do not inherit of _GNU_SOURCE.

n_err reflects the number of packets that the driver did not manage to

This is a temporary situation, those packets are not freed and the
application can still retry to send them later.
Hence, we can't count them as transmit failed.
