meson: Make verify-full-signature stand-alone

The new verify-full-signature config option requires that the legacy
config option verify-signature to be also enabled or it's a no-op.
Having to specify two different options to enable the full signature
verification is not user friendly.

Allow the verify-full-signature to turn on signature checking the same
as the verify-signature option, and add a comment that the new
verify-full-signature is the preferred option instead of the legacy
verify-signature.

Tested: Verified that compiling with -Dverify-full-signature=enabled
        defined WANT_SIGNATURE_VERIFY and WANT_SIGNATURE_FULL_VERIFY.
        Compiling with -Dverify-signature=enabled only enabled
        WANT_SIGNATURE_VERIFY. And either option compiled the
        image_verify.cpp file.
