refactor(frontends/lean): add 'attribute' command
...
The new command provides a uniform way to set declaration attributes.
It replaces the commands: class, instance, coercion, multiple_instances,
reducible, irreducible

feat(frontends/lean): increase binding power of ! and @
...
Remark: I did not add the constant "app".
Reason: It would break the standard library in many places.
Moreover, the current "max" is not just the binding power of
application, but also the binding power of identifiers, (, [, ...
It would be weird to call it "app"

feat(frontends/lean/elaborator): do not apply delayed_coercions on equation lhs
...
The variables in the equation lhs do not have type at preprocessing
time (i.e., their type is a metavariable). So, they may seem candidates
for delayed_coercions. If the coercions are injected, we will not be
able to pattern match. Thus, we disable coercions in this case.
