Danila Fedorin f23705a93e Add scoped quotation syntax for object-language programs ...

Introduce [spa_e| ... ] for Expr and [spa| ... ] for Stmt, scoped to the
Spa namespace via a dedicated syntax category and macro_rules. This removes
the deeply nested .andThen / .basic (.assign ...) boilerplate when writing
programs; Main.lean's test programs are rewritten to use it.
