feat(utils,types): DML Index can generate where SQL from a query builder (#7849)

what:

- introduces a simple query builder
- uses the query builder to tranform an object in where to SQL when applying indexes

```
Examples:
  { where: { column: null } } -> column IS NULL
  { where: { column: { $ne: null } } } -> column IS NOT NULL
  { where: { boolean_column: true } } -> boolean_column IS TRUE
  { where: { column: "value", another_column: { $ne: 30 } } } -> column = "value" AND another_column != 30
```

```
const user = model
  .define("user", {
    email: model.text(),
    account: model.text(),
    organization: model.text(),
  })
  .indexes([
    {
      on: ["organization", "account"],
      where: { email: { $ne: null } },
    },
    {
      name: "IDX-email-account-special",
      on: ["organization", "account"],
      where: {
        email: { $ne: null },
        account: null,
      },
    },
```
