feat(library/equations_compiler/util): try to improve performance of lemma generation
...
There are still performance problems. Lemma generation is fine, but the
kernel is timing out when checking the lemma. We need to provide hints
to the kernel to avoid the performance problem.

refactor(library/equations_compiler): new equation lemma generation
...
The idea is to generate a lemma based on the left-hand-side provided by
the user. This feature is essential for supporting the derived inductive
datatype constructors.

fix(library/type_context): complete_instance
...
The previous version was using typeclass inference to instantiate
arbitrary metavars in occurring in the input expression `e`.
This is incorrect. We should only use typeclass inference if the
metavariable is the argument of a function application (f ... ?m ...)
and the argument is marked and instance-implicit.
