[Feature request] Support implicit inversed relationship

[jiashengguo]

Support the below schema:

model User {
  id    Int    @id @default(autoincrement())
 // posts Post[].    no need to specify it in Zmodel,  ZenStack will generate it in the schema.prisma file.
}

model Post {
  id       Int  @id @default(autoincrement())
  author   User @relation(fields: [authorId], references: [id])
  authorId Int
}

Need naming convention rule to generate the inversed relation. Also, need a way to distinguish between one-to-one and one-to-many.

Take a reference of how EF handles it:

This would dramatically improve cases like this where it large schemas reference a common table like User
