feat(frontends/lean/structure): add option for controlling whether we automatically generate eta and projection-over-intro theorems for structures
...
It seems most of the time these theorems are not used at all.
They are just polluting the namespace.

refactor(library): mark 'decidable' theorems as definitions
...
If we don't do that, then any 'if' term that uses one of these theorems
will get "stuck". That is, the kernel will not be able to reduce them
because theorems are always opaque
