feat(frontends/lean): add '[semireducible]' attribute
...
This commit also renames the elements of reducible_status.
The idea is to use in the C++ implementation the same names used in the
Lean front-end.

fix(frontends/lean/parse_rewrite_tactic): corner case "rewrite ?(t)"
...
The token '?(' is used to represent inaccessible terms in recursive
equations. In the rewriter tactic, we want "rewrite ?(t)" to be parsed
as "? (t)".

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): add 'universe variable' command
...
We can declare variables anywhere. So, we must also be able do declare
"universe" variables anywhere. Here is a minimal example that requires
this feature
```
-- We want A and B to be in the same universe
universe variable l
variable A : Type.{l}
variable B : Type.{l}
definition tst := A = B
```
The following doesn't work because A and B are in different universes
```
variable A : Type
variable B : Type
definition tst := A = B
```
The following works, but tst is not universe polymorphic, since l is
one *fixed* global universe
```
universe l
variable A : Type.{l}
variable B : Type.{l}
definition tst := A = B
```
