Duplicate null in ENUM filters

[pantharshit00]

Reproduction: https://github.com/harshit-test-org/prisma2-client-442

Right now the enum filters are being generated with duplicate null types when they are marked as optional in the schema.

Update: This also applies to other Nullable Scalar filters:

export type NullableStringFilter = {
  equals?: string | null | null
  not?: string | null | NullableStringFilter | null
  in?: Enumerable<string> | null
  notIn?: Enumerable<string> | null
  lt?: string | null
  lte?: string | null
  gt?: string | null
  gte?: string | null
  contains?: string | null
  startsWith?: string | null
  endsWith?: string | null
}
