drm/amdkfd: enable missed single-step workaround for gfx12

When trap_ctrl.trap_after_inst is set, it is possible for a wave to
enter the trap handler, after single-stepping an instruction and a
save_context is raised, with only save_context set in excp_flag_priv.

Because excp_flag_priv.trap_after_inst is not reliably set, we need to
use the missed single-step workaround for gfx12 as well.

Also add wave_start and wave_end as exceptions that should be handled
by the 2nd level trap handler.
