Pull request description:

  ~~Based on: https://github.com/bitcoin/bitcoin/pull/16519~~
  Based on: #17933 (Time Machines are... shall we say... superior 😁)

  This PR allows us to perform Guix builds for the `x86_64-w64-mingw32` target. We do this _without_ splitting up the build script like we do in Gitian by using this newfangled alien technology called `case` statements. (This is WIP and might be changed to `if` statements soon)

Hint: To blow everything away, you may want to use:
$ git clean -xdff --exclude='/depends/SDKs/*'
Specifically, this will remove all files without an entry in the index,
excluding the SDK directory. Practically speaking, this means that all ignored
and untracked files and directories will be wiped, allowing you to start anew.

# --container run command within an isolated container

# Running in an isolated container minimizes build-time differences
# between machines and improves reproducibility
#
# --pure unset existing environment variables
#
# Same rationale as --container
#
# --no-cwd do not share current working directory with an
# isolated container
#
# When --container is specified, the default behavior is to share
# the current working directory with the isolated container at the
# same exact path (e.g. mapping '/home/satoshi/bitcoin/' to
# '/home/satoshi/bitcoin/'). This means that the $PWD inside the
# container becomes a source of irreproducibility. --no-cwd disables
# this behaviour.
#
# --share=SPEC for containers, share writable host file system
# according to SPEC
#
# --share="$PWD"=/bitcoin
#
# maps our current working directory to /bitcoin
# inside the isolated container, which we later cd
# into.
#
# While we don't want to map our current working directory to the
# same exact path (as this introduces irreproducibility), we do want
# it to be at a _fixed_ path _somewhere_ inside the isolated
# container so that we have something to build. '/bitcoin' was
# chosen arbitrarily.

# The isolated container has no network access as it's in a

# should have been downloaded prior to this invocation.
