gnu: texlive: Reinstate the monolithic texlive package.

This goes back essentially to commit
ad457d01147b8d6fcb4ee64b2dc2d699caa1d1ee and defines the monolithic texlive
packages independently of the modular ones. It also downgrades their
version to 2021. Not using dashes in the names of texlivebin and
texlivetexmf prevents the profile hook for font mapping from being run
during the command "guix shell -D texlive".

* gnu/packages/tex.scm (texlive-bin-full): Remove variable.
(biber): Remove variable deprecation.
(texlive-texm, texlive): Move variables from here...
* gnu/packages/texlive.scm (texlivetexm, texlive): ...to this new file.
(%texlive-date, %texlive-version, %texlive-tag, %texlive-revision,
texlive-extra-src, texlive-texmf-src, texlivebin): New variables.
(biber): Add variable again.
* gnu/packages/patches/biber-adapt-perl-5.36.patch: Add file again.
* gnu/local.mk (GNU_SYSTEM_MODULES, dist_patch_DATA): Register files.

+Subject: [PATCH] Adapt to Perl 5.36
+
+A developmental release of Perl 5.36.0 fails to run tests with:
+
+    $ perl -Ilib t/basic-misc.t
+    1..72
+    Can't modify undef operator in scalar assignment at lib/Biber/Section.pm line 433, near "undef;"
+    Compilation failed in require at lib/Biber.pm line 24.
+    BEGIN failed--compilation aborted at lib/Biber.pm line 24.
+    Compilation failed in require at t/basic-misc.t line 11.
+    BEGIN failed--compilation aborted at t/basic-misc.t line 11.
+    # Looks like your test exited with 255 before it could output anything.
+
+This is because of a missing semicolon between commands in
+del_everykeys(). The new perl is more strict and raises a compile-time
+error:
+
+    $ perl -e '$a = undef $b = undef;'
+    Can't modify undef operator in scalar assignment at -e line 1, near "undef;"
+    Execution of -e aborted due to compilation errors.
