qcacmn: Refine roam stats frame subtypes in a QCA vendor attribute

Enumeration qca_wlan_roam_stats_frame_subtype defines the various frame
subtypes which may be collected by the driver and reported via the
QCA_WLAN_VENDOR_ATTR_ROAM_STATS_FRAME_SUBTYPE attribute.

Two of the enumerators are:
* QCA_WLAN_ROAM_STATS_FRAME_SUBTYPE_PREAUTH
* QCA_WLAN_ROAM_STATS_FRAME_SUBTYPE_REASSOC

These were initially defined and used to respectively report
Authentication Response and Reassociation Response frames.

Now there is a requirement to also report Authentication Request and
Reassociation Request frames. In order to satisfy this requirement,
add two new enumerators:
* QCA_WLAN_ROAM_STATS_FRAME_SUBTYPE_AUTH_REQ
* QCA_WLAN_ROAM_STATS_FRAME_SUBTYPE_REASSOC_REQ

Note that the first of these uses the standard term "AUTH" instead of
the confusing term "PREAUTH" used previously.

And to align with that naming, and in order to clearly show the usage
of the original enumerators, rename them to:
* QCA_WLAN_ROAM_STATS_FRAME_SUBTYPE_AUTH_RESP
* QCA_WLAN_ROAM_STATS_FRAME_SUBTYPE_REASSOC_RESP

Furthermore, Authentication Request/Response frame refers to the
Authentication frames sent by the non-AP STA and AP, respectively.

And finally, to support backward compatibility with applications using
the original enumerators, redefine those in terms of the new names.
