i386/sev: Move sev_launch_finish to separate class method

When sev-snp-guest objects are introduced there will be a number of
differences in how the launch finish is handled compared to the existing
sev-guest object. Move sev_launch_finish() to a class method to make it
easier to implement SNP-specific launch update functionality later.
