Move tpm2 and getty support to -udev subpackage

We want getty@.service to be enabled through presets, so that the
autovt@.service alias is created (or not). See
https://fedoraproject.org/wiki/Changes/UseKmsconVTConsole.
getty@.service was changed upstream to have a full [Install] section,
but we need to handle installation of the unit here. This will now
create the autovt@.service alias when enabled.

While looking at this, I noticed that the getty units are in the main
package. They don't have to be, virtual terminals are only available
if we have "hardware", i.e. the -udev subpackage is appropriate.
Same for the tpm2 stuff.

I considered leaving getty.target in the main package, so that
foreign units that refer to it don't generate a warning about missing
units, but I think that those packages should not be installed on
systems without systemd-udev, so it's fine if the warning appears.
