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.

Namely, libplacebo (since it is now unconditional) and VideoToolbox.

And some refactors:
- Remove dev output (cycle detected in build of <mpv> in the references of
output 'dev' from output 'out')
- Env vars inside env
- Remove nested with
Swift support doesn’t seem to work with back-deployed dylibs, so set the
deployment target to 10.15 to force Swift to link against the system
Swift libraries. The change to use the Swift stdenv fixes the errors
reported in #214944.
mpv ships with a wrapper-script umpv that adds files to the queue of a currently
running mpv instance. This script does not take any options.
The desktop file for it simply substituted mpv with umpv in mpv.desktop,
resuting in an incorrect desktop file with `Exec=umpv --player-operation-mode=pseudo-gui -- %U`.
This resulted in umpv adding bogus files to the queue.
