it cannot fold the recursive applications.

1e6550eda6 feat(kernel/default_converter): take into account the 'theorem' annotations in the converability checker 
The idea is that we should seldon need to unfold theorems.
The convertability checker should use that.
When the convertability checker was implemented, theorems were opaque in
Lean. So, this hint was not needed.

This modification is another workaround for the performance problem with
the migrate command at library/data/real/division.lean.
This solution is better than applying proof irrelevance eagerly because
it also addresses similar problems in the HoTT library which does not
support proof irrelevance.

This commit also enables the conv_opt for all theorems.
