When we ship LLVM 16, <ranges> won't be considered experimental anymore.
We might as well do this sooner rather than later.

All supported compilers that support C++20 now support concepts. So, remove
`_LIB_LIBCPP_HAS_NO_CONCEPTS` in favor of `_LIBCPP_STD_VER > 17`. Similarly in
the tests, remove `// UNSUPPORTED: libcpp-no-concepts`.

As discovered in D117817, `std::ranges::input_range<Holder<Incomplete>*[10]>`
hard-errored before this patch. That's because `input_range` requires
`iter_rvalue_reference_t`, which requires `iter_move`, which was
not ADL-proofed.
Add ADL-proofing tests to all the range refinements.
`output_range` and `common_range` shouldn't be affected,
and all the others subsume `input_range` anyway, but we might as
well be thorough.

AFAICT, Cpp17InputIterators are not required to be default constructible,
since that requirement is added in Cpp17ForwardIterator. Hence, our
archetype for Cpp17InputIterator should not be default constructible.
Removing that constructor has a ripple effect on a couple of tests that
were making incorrect assumptions. Notably:
- Some tests were using cpp17_input_iterator as a sentinel for itself.
That is not valid, because a cpp17_input_iterator is not semiregular
anymore after the change (and hence it doesn't satisfy sentinel_for).
- Some tests were using a stride-counted cpp17_input_iterator as the
sentinel for a range. This doesn't work anymore because of the problem
above, so these tests were changed not to check stride counts for
input iterators.
- Some tests were default constructing cpp17_input_iterator when a simple
alternative was available -- those have been changed to use that alternative.

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.

* adds `sized_range` and conformance tests
* moves `disable_sized_range` into namespace `std::ranges`
* removes explicit type parameter
Implements part of P0896 'The One Ranges Proposal'.
