glasgow: 0-unstable-2025-01-26 -> 0-unstable-2025-07-28

In addition to bringing all the new features since then, upstream now
uses the same sdcc version, and with an additional normalization phase,
we come up with exactly the same firmware as them (and validate this).

We previously had both the committed firmware blob from upstream, as
well as our built firmware in our output, and only used the upstream one
due to a packaging bug (changed path).

Dependencies were slightly reordered, instead of propagatedBuildInputs
we now use dependencies, and build-system is used instead of
nativeBuildInputs to more align with python package style. I also
documented why pytestCheckHook cannot be used.
