Define QCA vendor per-enum 64-bit pad attributes

When writing 64-bit attributes into the netlink buffer, senders may
add a padding attribute to allow the payload of the 64-bit attribute
to be 64-bit aligned. For QCA vendor attributes, currently the
attribute QCA_WLAN_VENDOR_ATTR_PAD in enum qca_wlan_vendor_attr is
defined for this purpose.

Unfortunately, when adding attributes to the netlink buffer, all
attributes at a given level of nesting must be defined in the same
enum so that they can be unambiguously parsed. This means that
QCA_WLAN_VENDOR_ATTR_PAD can only be used to pad 64-bit attributes
defined in enum qca_wlan_vendor_attr.

There are many other QCA vendor enums which define 64-bit attributes,
so add a pad attribute to all of them so that the 64-bit attributes
can be unambiguously padded.
