(cherry picked from commit 4a7851b0)

Packages are removed from msys2.org after 21 months. Since the 6.x branch may
have a longer lifetime, it is safer to have our own mirror for the specific
packages that we need.

Incidentally, this means that the JSONlab submodule is no longer needed, so it
is removed in the present commit.

Closes: #1907

Ref. #1907

Incidentally, drop workarounds for pkg-config files of HDF5 and MatIO, since
the problems have been fixed upstream.

By the way, simplify the dependency build system by removing unused SLICOT
builds.

Mostly working. The testsuite remains to be done.

In particular, windows/deps/mkoctfile64 is modified to print its version number
on stdout instead of stderr. This is what the standard mkoctfile does, and it
allows easier capture of the output from Meson.

Unpacked files may already be present due to GitLab CI caching.

Bug introduced in 39c2cba1.

Ref. #1878

– enable maximum optimization (-O3), which in particular triggers code
  auto-vectorization
– raise the minimal architectural requirement to match MSYS2 policy
  (roughly requires CPUs from ~2006/7+)

In particular, now ship GCC 13 for the use_dll option.

Also move some useful documentation to doc/.

HDF5 itself now drags a lot of new dependencies (curl and its own deps,
openssl).
