Rename entry executable to drop "-core" suffix (#551)

Rename the main entry executable from
`git-credential-manager-core(.exe)` to simply
`git-credential-manager(.exe)`, now that the older GCM4W has been
removed from the Git for Windows project as an option (and the GCMC
project has been renamed).

We do **not** rename the Debian package ID, nor the Homebrew Cask name
yet as this will require more thought forr migration.

To help with migration somewhat, create symlinks and
shim/copy-executables for the original executable name
"git-credential-manager-core(.exe)" for consumers who have not updated
to the new version.
    
We detect if the consumer is launching us via the "-core" symlink or
executable shim by consulting the platform-native APIs to get the
original "argv[0]". All of the .NET APIs sadly don't give us the real
"argv[0]", so we need to use native APIs...
    
If we detect use of the old name, print a warning that the user should
update their configuration, and a help link for more information.
