boards: nxp: Support NXP ENET_1G on mimxrt1170_evk

Support NXP ENET_1G on mimxrt1170_evk/mimxrt1176/cm7 platform. Added test configuration sample.net.zperf.nxp_enet1g and documented the usage of the ethernet driver with ENET_1G peripheral. Fixes: zephyrproject-rtos#66348 Signed-off-by: Stanislav Poboril <stanislav.poboril@nxp.com>

+ENET1G Driver
+=============
+
+Current default of ethernet driver is to use 100M Ethernet instance ENET.
+To use the 1G Ethernet instance ENET1G, include the overlay to west build with
+the option `-DEXTRA_DTC_OVERLAY_FILE=nxp,enet1g.overlay` instead.
