[PATCH] wpa_supplicant: Add CONFIG_NO_WPA stubs for Security Profile support

[Chaitanya Tata]

The Security Profile feature (IEEE P802.11bn/D2.0) added
wpa_sm_set_security_profile(), sec_prof_get(),
security_profile_akm_matches(), security_profile_build_sta() and
security_profile_build_empty(), all of which are called
unconditionally from wpa_supplicant.c/sme.c, but are only implemented
in src/rsn_supp/wpa.c, src/rsn_supp/wpa_ie.c and src/common/
wpa_common.c. Those source files are not built when CONFIG_NO_WPA is
set, so wpa_supplicant fails to link with undefined references to
all five functions.

Add CONFIG_NO_WPA stubs for them, following the existing pattern used
for the rest of the WPA/RSN API in these headers. Verified that
wpa_supplicant now builds and links with CONFIG_NO_WPA=y (it
previously failed with the errors above).
