Enable dialect specific behaviours in the parser (#254)

Browse source 
* Change `Parser { ... }` to store the dialect used:
    `Parser<'a> { ... dialect: &'a dyn Dialect }`

    Thanks to @c7hm4r for the initial version of this submitted as
    part of https://github.com/ballista-compute/sqlparser-rs/pull/170

* Introduce `dialect_of!(parser is SQLiteDialect |  GenericDialect)` helper
    to branch on the dialect's type

* Use the new functionality to make `AUTO_INCREMENT` and `AUTOINCREMENT`
  parsing dialect-dependent.
