Add Android vendor command and event definitions

Introduces a new header file to document the attributes
for Android-specific vendor commands and events within
Linux Wireless. These are used to control advanced
features in wireless chips, all associated with the
Google OUI (F4:F5:E8). Driver, firmware, wpa_supplicant
and other C code implementing Android vendor commands/events
should refer to this file.
