core, w32: Add w64 handling for regkeys

Browse Source 
* src/w32-util.c (_gpgme_get_gpg_path): Use new defines.
(GNUPG_REGKEY_2): x64 aware regkey as used by GnuPG in Gpg4win 2.x
(GNUPG_REGKEY_3): x64 aware regkey as used by GnuPG in Gpg4win 3.x
(_gpgme_get_gpgconf_path): Use new regkeys. Add another fallback.

--
This should fix more "unsupported protocol" issues if Gpg4win /
GnuPG is installed in a non standard path on 64bit systems.

The regkey handling is similar to that of gpgex and gpgol.
