ce674d2d43 feat(library/tactic): execute Lua tactics using coroutines
This is very important when several Lua tactics are implemented in the
same Lua State object.  In this case, even if we use the par
combinator, a Lua tactic will block the other Lua tactics running in
the same Lua State object.

With this commit, a Lua tactic can use yield to allow other tactics
in the same State object to execute.

d87ad9eb7e refactor(util/lua): propagate C++ Lean exceptions in Lua
The following call sequence is possible:
C++ -> Lua -> C++ -> Lua -> C++

The first block of C++ is the Lean main function.
The main function invokes the Lua interpreter.
The Lua interpreter invokes a C++ Lean API.
Then the Lean API invokes a callback implemented in Lua.
The Lua callback invokes another Lean API.
Now, suppose the Lean API throws an exception.
We want the C++ exception to propagate over the mixed C++/Lua call stack.
We use the clone/rethrow exception idiom to achieve this goal.

Before this commit, the C++ exceptions were converted into strings
using the method what(), and then they were propagated over the Lua
stack using lua_error. A lua_error was then converted into a lua_exception when going back to C++.
This solution was very unsatisfactory, since all C++ exceptions were being converted into a lua_exception, and consequently the structure of the exception was being lost.

4c5ec53a44 chore(util/lua): remove dead code
I removed lua_module helper class because it does not work.
The problem is that the linker may eliminate ignore a object file that contains a lua_module global object used for initialization. When this happens, the associated Lua bindings will not be exposed in the Lua API.

feca9dbdf8 refactor(bindings/lua): move to frontends/lua
Lua API is an integral part of Lean. It does *not* have the same status
of external APIs (e.g., Python) we will add in the future.

We will reserve the directory bindings for external APIs for using Lean
as a library.

956f203a55 refactor(bindings/lua): move Lua bindings to the file associated with them
The directory bindings/lua was getting too big and had too many dependencies.
Moreover, it was getting too painful to edit/maintain two different places.
Now, the bindings for module X are in the directory that defines X.
For example, the bindings for util/name.cpp are located at util/name.cpp.

The only exception is the kernel. We do not want to inflate the kernel
with Lua bindings. The bindings for the kernel classes are located
at bindings/kernel_bindings.
