In preparation for the deprecation of `stdenv.isX`.
These shorthands are not conducive to cross-compilation because they
hide the platforms.
Darwin might get cross-compilation for which the continued usage of `stdenv.isDarwin` will get in the way
One example of why this is bad and especially affects compiler packages
https://www.github.com/NixOS/nixpkgs/pull/343059
There are too many files to go through manually but a treewide should
get users thinking when they see a `hostPlatform.isX` in a place where it
doesn't make sense.

- xcodewrapper nix derivation has been updated to now accept a list of acceptable versions.
- allowHigher is now removed
- this matches closely to what we use for building react-native with nix at status-mobile repo
ref -> https://github.com/status-im/status-mobile/blob/develop/nix/pkgs/xcodeenv/compose-xcodewrapper.nix
- The key change done here is that now xcodewrapper checks Xcode versions at runtime instead of build time. This helps us to show warning messages when underlying environment does not have the Xcode version we want to support.
* doc: add stdenv passthru chapter
Broad strokes:
- create the chapter
- move existing stdenv passthru coverage into it
- move out-of-place coverage of passthru.tests from the stdenv meta chapter into it
- (try to) apply 1-sentence-per-line to text I've touched
- add legacy anchors for everything moved
- update existing links to the new anchors
- add tentative motivating text
- make nixpkgs-internal links relative/branchless
razor: if it is only ever needed by contributors, which is likely if links
refer to the latest revision of the source code, then it's for
the contributor guide

Fixes#298285, alternative to #300386.
As suggested in #298285 `lib64` was renamed to `lib`, so just doing the same
as for `lib64` seems to fix the issue.
See also recent discussion in #300386.
The nixpkgs-unstable channel's programs.sqlite was used to identify
packages producing exactly one binary, and these automatically added
to their package definitions wherever possible.
These files don't even parse using `nix-instantiate --parse`:
> error: undefined variable 'haskell-mode'
> error: undefined variable 'lib'
While these issues could be trivially fixed, the fact that these files
are not even parsable by nix-instantiate shows me that they are probably
unnecessary.
