Fix backend selection logic
In some cases the backend selection was not working properly:
- Key derivation, wrapped key import: the backend compatibility was not
checked at all. This resulted in a possibility of saving an exportable
key in TZ backend which normally is not allowed.
- Encrypted initial values could have been imported to incompatible SW
backend if the TZ backend fails to initialize or the SW backend is
forced.
The Decider API was also unclear and different policies were in force

* Keep the policy in a single place.
* Return a prioritized list of backends compatible with given use case.
* Add backend check to key derivation and wrapped key import.

Simplify DB::Row/Token extraction
For wrapped key export we need to pass 1 object to be wrapped by
another. GObjUPtr is insufficient as it loses information about the
specific type. We'll need that info in TZ backend.
The wrapping API can be then made look as follows:
RawBuffer GObj::wrap(const CryptoAlgorithm ¶ms,
const Token &keyToWrap,
const Password &keyToWrapPass);

Add an ECDH+KBKDF example in form of a doxygen snippet. The code used in it is
compiled together with the project.
Disclaimer:
I don't know how to generate Tizen API documentation. Basing on other projects
I made an assumption that doxygen's EXAMPLE_PATH points to doc subdirectory.
With such assumption, vanilla doxygen generates the code snippet properly.
