Christopher Di Bella 773ae44124 [libcxx][nfc] prefixes test type `input_iterator` with `cpp17_`
C++20 revised the definition of what it means to be an iterator. While
all _Cpp17InputIterators_ satisfy `std::input_iterator`, the reverse
isn't true. D100271 introduces a new test adaptor to accommodate this
new definition (`cpp20_input_iterator`).

In order to help readers immediately distinguish which input iterator
adaptor is _Cpp17InputIterator_, the current `input_iterator` adaptor
has been prefixed with `cpp17_`.

Martin Storsjö 8d0dfa0d57 [libcxx] Reenable ranges for clang-cl
This reverts a224bf8ec4 and fixes the
underlying issue.

The underlying issue is simply that MSVC headers contains a define
like "#define __in", where __in is one macro in the MSVC Source
Code Annotation Language, defined in sal.h

Just use a different variable name than "__in"
__indirectly_readable_impl, and add "__in" to nasty_macros.h just
like the existing __out. (Also adding a couple more potentially
conflicting ones.)

Christopher Di Bella 7c17731596 [libcxx][ranges] adds `ranges::range`, `ranges::common_range`, and range aliases
* `std::ranges::range`
* `std::ranges::sentinel_t`
* `std::ranges::range_difference_t`
* `std::ranges::range_value_t`
* `std::ranges::range_reference_t`
* `std::ranges::range_rvalue_reference_t`
* `std::ranges::common_range`

`range_size_t` depends on `sized_range` and will be added alongside it.

Implements parts of:
