1dd8cbfbc6 build: don't compress macOS DMG (fanquake)
Pull request description:
Skip compressing the macOS DMG, and drop related build steps and dependencies. Uncompressed the DMG increases from ~16mb to ~30mb, which compared to other software a user may download, (Firefox 125mb, VLC 52mb, Open Office 176mb), is still relatively small. When contrasted against the 100's of GB of blockchain data a node will download, an additional 15mb to get the release binary, isn't much additional overhead. Note that if / when we build with LTO enabled for releases, this size will shrink back down significantly again.
`native_libdmg-hfsplus` is not maintained, and I doubt the DMG creation feature will ever be fixed. If at some point `xorrisofs` supports compressing dmgs, we could enable that.

The explicit statement that an Apple Developer Account is required in
order to obtain the SDK is buried within the "Deterministic macOS DMG
Notes" section. It should be the first thing mentioned under the "SDK
Extraction" section. The reason to do this is to set expectations of
what is required before starting any steps or clicking on links.
This fixes the issue by doing just that; moving this information to the
"SDK Extraction" section. Now that the information is moved, this also
deletes unnecessary SDK related notes from the "Deterministic macOS DMG
Notes" section. It is not necessary to explain under what sub-directory
'most' of the important files are inside of the 'Xcode.app'.
The previous link wasn't accessible for me, this adds some instructions
given to me by Hebasto on #bitcoin-core-builds as well as a shasum for
the archive to quickly check the downloaded one is the right one before
processing with the entire Guix build.
This also corrects a link to an older version of the SDK currently in
use.

xorriso and its mkisofs/genisoimage emulation alter-ego xorrisofs are
more maintained, and has the right toggles for us to achieve output
determinism without using blunt tools like faketime.
In this commit, we use xorrisofs from the build environment rather than
building it ourselves using depends. This is not necessary and can be
changed in the future.
From https://wiki.debian.org/genisoimage?action=recall&rev=11 :
> The classical command line interface for production of ISO 9660
> filesystem images is the option set established by program mkisofs.
> For reasons of licensing and other problems with its author, Debian
> ships a fork of mkisofs, called genisoimage, which was split off in
> 2006 and then developed independently.
>
> Meanwhile, genisoimage gets no new features and not even bug fixes. It
> is first choice only if its options -udf or -hfs are needed.
>
> Replacement in most uses cases, especially for bootable ISO 9660
> filesystems, archiving, and backup, is xorrisofs which starts the -as
> mkisofs emulation mode of program xorriso.
Rather than two lots of logic doing roughly the same thing, dependent on if
you're compiling on Linux or macOS, combine the .DS store generation into
macdeployqtplus.
This also removes the -fancy and -volname options.
Previously, we did not include the macOS SDK libc++ headers in our SDK
creation process and instead used whichever libc++ headers shipped with
the clang package we downloaded in depends.
This change adds a script (which works on both GNU/Linux and macOS) to
correctly generate the macOS SDK including the libc++ headers. This can
be thought of as a simplified rewrite of tpoechtrager's script:
d3392f4eae/tools/gen_sdk_package.sh
The location within the SDK where we place the libc++ headers is chosen
such that clang's search path detection logic for sysroots would pick up
the headers properly.
We also document this change.
