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`.

Fixed in counted_iterator and transform_view::iterator.
The LWG issue also affected elements_view::iterator, but we haven't
implemented that one yet, and whoever does implement it will get
the fix for free if they just follow the working draft's wording.
Drive-by stop calling `.base()` on test iterators in the test,
and improve the transform_view::iterator/sentinel tests.

Eliminate a bogus operator== overload.
Also, check more intermediate steps in the logic we're checking here.
Some of this simplification is possible only now that we've implemented
more of <ranges>.

The unique (ha!) thing about this range type is that it's move-only.
Its contiguity is unsurprising (most of our test ranges are contiguous).
Discussed in D111231 but committed separately for clarity.
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.
