mesh: Add support for HE mode

Browse Source 
Mesh points can partially support HE features (when requiring no
controlling STA/AP) as long as hardware supports it. The kernel just
requires support for HE mesh and wpa_supplicant can forward the peer
capabilities to the kernel for further processing.
