Improve replacement of return type for methods from Query\Builder (#1575)

* Add return type `|static` to Query\Builder methods (#1574)

* Replace return type Query\Builder with Eloquent\Builder (#1574)

* Replace return type Query\Builder only for facade Eloquent (#1574)

* Add special return type replacement for Macros of \Eloquent

* Restrict special return type to methods from Eloquent\Builder and Query\Builder

* Do not overwrite return type in normalizeReturn() with conditional call of setType()

* Use generic return type for builder methods in \Eloquent

* composer fix-style
