feat: atomic number field updates (#13118)

Based on https://github.com/payloadcms/payload/pull/13060 which should
be merged first
This PR adds ability to update number fields atomically, which could be
important with parallel writes. For now we support this only via
`payload.db.updateOne`.

For example:
```js
// increment by 10
const res = await payload.db.updateOne({
  data: {
    number: {
      $inc: 10,
    },
  },
  collection: 'posts',
  where: { id: { equals: post.id } },
})

// decrement by 3
const res2 = await payload.db.updateOne({
  data: {
    number: {
      $inc: -3,
    },
  },
  collection: 'posts',
  where: { id: { equals: post.id } },
})
```
