Add comments to functions in chainable_api. Depending on the method,
these comments add some additional context or details that are relevant
when reading the function, link to the actual docs at gorm.io/docs, or
provide examples of use. These comments should make GORM much more
pleasant to use with an IDE that provides hoverable comments, and are
minimal examples.
Also add in-code documentation to FirstOrInit and FirstOrCreate.
Almost all examples are directly pulled from the docs, with short
comments explaining the code. Most examples omit the `db.Model(&User{})`
for brevity, and would not actually work.

* Inherit clone flag (NewDB) on transaction creation
I find it very reassuring to know that after a finisher API, I get a clean db object for my next queries.
If you look at the example in https://gorm.io/docs i’d see many queries running one after the other.. but in reality they wouldn’t work as the they are portrayed and that’s because in default mode NewDB is false and will make all the clauses stay even after a finisher API.
My solution is just to have the value of the clone flag in the “parent” db object, be injected to its children transactions.
