The type `MoveOnlyForwardRange` violates the precondition stated in
`view.interface.general`. Specifically, the type passed to
`view_interface` shall model the `view` concept. In turn, this requires the
type to satisfy `movable` concept (and others), but this type
`MoveOnlyForwardRange` does not satisfy the `movable` concept.
Add a move assignment operator so that `MoveOnlyForwardRange` satisfies the
`movable` concept. While we're here, ensure the neighboring types that inherit
from `view_interface` also satisfy the `view` concept to avoid similar issues.

Since we officially don't support several older compilers now, we can
drop a lot of the markup in the test suite. This helps keep the test
suite simple and makes sure that UNSUPPORTED annotations don't rot.
This is the first patch of a series that will remove annotations for
compilers that are now unsupported.

Adds a new CMake option to disable the usage of incomplete headers.
These incomplete headers are not guaranteed to be ABI stable. This
option is intended to be used by vendors so they can avoid their users
from code that's not ready for production usage.
The option is enabled by default.
