Get the viewer installable on Debian arm64

The Debian version supported is 13 (trixie), because that's the version
I could install on my M1, hence the Boost default version is 1.83 & we
can use system's OpenJPEG 2.5.3.
Somehow CMake's FindOpenGL wasn't effective, but we can get around this
by setting the GL libraries paths when running cmake.
Debian aarch64 suffers from the same problem Fedora aarch64 had when
compiling libcurl, and it's assumed that it's Linux aarch64 thing.
When trying to build ColladaDOM when building the viewer, it couldn't
find Boost somehow, so building ColladaDOM is done in configuration
stage instead.
Upstream Variables.cmake is full of assumptions regarding architecture,
and ARCH is used in many places already for Debian/Ubuntu, so we have to
make sure ARCH is set with the correct value at the root level.
Pipewire on trixie is also too new, so it's cancelled here.
Some dependencies have the t64 suffixes on them, just like the currently
supported Ubuntu (because I guess 24.04 *is*, based on trixie).
The executable still crashes when launched on my M1, however, but we'll
commit the progress so far for now.
