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
```

feat(kernel/inductive): K-like reduction in the kernel
...
Given (H_1 : a = a), we have that
eq.rec H_2 H_1
reduces to H_2
This is not exclusive to equality.
It applies to any inductive datatype in Prop, containing only one
constructor with zero "arguments" (we say they are nullary).
BTW, the restriction to only one constructor is not needed, but it is
does not buy much to support multiple nullary constructors since Prop is
proof irrelevant.
