other programming languages.

Syntax objects.

defined in C++ yet.

280e7bb006 feat(library/init/lean/attributes): add TagAttributes 
`TagAttribute`s are implemented on top of the low level Attribute API,
and `PersistentEnvExtension`.
This is just the first attribute on a series of attributes we are
going to implement using Lean itself.

7909d86e5d feat(library/init/lean): Syntax objects with new SyntaxNodeKind and Substring, and arrays instead of lists 
We can use `SyntaxNodeKind.id : Nat` to implement maps from kind to
values using arrays.

55626ba60d chore(library/init/lean): disable new frontend for now 
We are going to start making drastic changes in the parser,
elaborator, attributes, etc. Examples:
- No View objects. I am going to implement match_syntax.
- No RecT in the parser. I am going to implement parser extensions
using an approach similar to the one I used to implement environment
extensions.
- No Parsec. I will use an approach similar to the one used in the
experiment https://github.com/leanprover/lean4/tree/master/tests/playground/parser

It is easier to perform these changes with the new frontend disabled.
I will slowly re-active it as I apply the changes.

67a4ebbde6 feat(library/init/lean/attributes): low level attribute registration, and frontend attribute actions 
Remark: the attribute actions used by the frontend are all in IO.
These actions access attributes by name, and need access to the IO.ref
that contains all registered attributes in the system.
