0f07230eb9 DPP2: Add privacyProtectionKey into Configurator backup/restore
This allows the privacyProtectionKey to be transferred to a new
Configurator similarly to the way c-sign-key is transferred.

88d3f43bd3 DPP2: Replace OneAsymmetricKey version number (v2 to v1)
DPP tech spec was modified to use v1(0) instead of v2(1) for the
OneAsymmetricKey in the Configurator backup structure to match the
description in RFC 5958 Section 2 which indicates v2 to be used when any
items tagged as version 2 are included. No such items are actually
included in this case, so v1 should be used instead.

Change OneAsymmetricKey generation to use v1(0) instead of v2(1) and
parsing to accept either version to be used. This is not backwards
compatible with the earlier implementation which requires v2(1) when
parsing the received value.

0f58c88fc3 DPP2: Fix CONFIG_DPP2=y build with OpenSSL 1.0.2
This file needs the EVP_PKEY_get0_EC_KEY() compatibility wrapper just
like other DPP source code files using this function.

Fixes: 21c612017b ("DPP: Move configurator backup into a separate source code file")
