This commit switches `model::Type::ID` from being a GUID to be a
progressive number, in order to make things easier for humans.
On top of this, this commit introduces the following changes:
* TypeCopier: import all the necessary PrimitiveTypes and improve
handling of CustomName.
* Move Kind as the last field of the key of each TupleTree type used in
an `UpcastablePointer`.
* Update the ground truth of tests to ignore the `CustomName` in favor
of focusing on `OriginalName`.
* Increase adoption of `model::Binary::makeType`, equivalent to
`Binary.recordNewType(makeType<model::*Type>())`.
revng.model.__init__ would dynamically import the latest version of
the model when imported, however this would break IDE hints as the
classes would not be properly detected. Instead we now manually
specify the last version in the __init__.py file.
Implement a constructor override for model classes that checks that the
constructor does not have positional arguments passed to it. This can
be dropped post-3.10 since it is implemented natively by kw_only.
