[L-Mario564]

Addresses #535 and #574.

This PR adds support for .orderBy() and .limit() in update and insert statements in MySQL and SQLite.

await db.insert(users).values([
  { name: 'Barry', verified: false },
  { name: 'Alan', verified: false },
  { name: 'Carl', verified: false },
]);

/*
 * Only update the first two rows, ordering by name ascending. Ending up with the following rows:
 * { name: 'Alan', verified: true },
 * { name: 'Barry', verified: true },
 * { name: 'Carl', verified: false }
*/
await db.update(users).set({ verified: true }).limit(2).orderBy(asc(users.name));
