The installer is probably the most complex packaging format so one of the
biggest examples of packaging love over the years into it in our repo.
But the readability of installer scripts... leave a lot to be desired.
Now, the main script is organized following the order of installer pages
with some comments. This will make easier to future contributors work
(but this commit probably isn't perfect since it's a big change to read)
The Inno installer scripts contents (only 3 files: files, gimp3264 and
32on64) and filenames have been organized, making them much easier to
read, and slightly less hardcoded so less prone to being misunderstood
and pervasively receiving packaging stuff.
Just to be clear, one more time: the Inno installer (or future MSIX)
scripts never should be the center of attention. This "installcentrism"
caused a domino effect of partially "abandoning" the packaging, build.sh
and the meson scripts, which explains the existence of this MR...
(Some things still hardcoded since wildcards in Inno are very limited.
Also, the rational ordering principles of this MR were not applied since
these scripts are heavily based on the x86 .zip package and changing the
order of things here, according to my tests, breaks things quite easily)
