Some modules export modules that they don't import (i.e. that their header doesn't directly include). That sometimes works when the exported submodule is in the same module, but when the `std` mega module is broken up (D144322), some of the exports stop working. Make the exports and includes consistent, either by adding includes for the exports, or by removing exports for missing includes.
The `concepts.equality_comparable` export in `std.iterator.__iterator.concepts` isn't doing anything because 1) it's resolved as `std.iterator.__iterator.concepts.equality_comparable` and 2) there's a `__concepts` submodule in between `std.concepts` and `equality_comparable`. Fix it to be `std.concepts.__concepts.equality_comparable`.
<span> is listed in both `std.span` and `std.experimental.span`. Delete the latter module.
There is no `__errc` module or header, so remove that export from `std.system_error`.

These macros are always defined identically, so we can simplify the code a bit by merging them.

We already have a clang-tidy check for making sure that `_LIBCPP_HIDE_FROM_ABI` is on free functions. This patch extends this to class members. The places where we don't check for `_LIBCPP_HIDE_FROM_ABI` are classes for which we have an instantiation in the library.

This file was added before we started granularizing the headers, but is essentially just a granularized header. This moves the header to the correct place.
