gnu: TeX Live: Update to TeX Live 2021

Use version 20210325 for the tarballs, which is the latest one available on
the historical releases repository. And use subversion tag 2021.3 which is
the latest one available as well.

TeX Live dropped support for using the system’s poppler library after the
2020 version.  Quoting from `m4/kpse-xpdf-flags.m4`:

  # Support for our semi-homegrown libs/xpdf library. This is derived
  # from xpdf source code, but xpdf does not distribute it as a library.
  # It is used by pdftex (and nothing else) to read PDF images.
  # Other engines use the semi-homegrown pplib library (q.v.) for that.

  # The well-known poppler library is also originally derived from xpdf
  # source code, but has been greatly revised and extended. TL used to
  # (sort of) support poppler as the system xpdf, but after the TL 2020
  # release we dropped this, because we switched XeTeX to use pplib, and
  # nothing else used poppler. (No engines ever used poppler to generate
  # their PDF output).
  #
  # poppler is aggressively developed, with requirements for new compilers
  # and language versions. That's fine for them, but since we don't need
  # anything new, it has become too time-consuming and problematic to
  # continue to support it in the TL sources, when we don't have any
  # requirement for it.

Therefore the main change in this commit is making the texlive-bin package
use the embedded pplib and xpdf libraries.

Another noteworthy change is to texlive-latex-l3packages, which now needs
to ship a few pre-generated files that cannot be reproduced during the
build process (the comments in the package definition have more details).
