texlive: Add spkg-configure.m4 and system package information; remove install script

[mkoeppe]

Right now presence of tex is not tested, and texlive is included in system packages of _recommended.

In this ticket, we associate the tex system package with texlive instead.

We also test presence of latex packages that are needed for building the sage pdf documentation and make texlive a dependency of sagemath_doc_pdf.

We remove the install script due to lack of use and maintenance (#21922). Installing tex should not be the concern of SageMath.

texlive-lang-european
texlive-lang-french
texlive-lang-german
texlive-lang-italian

as far as I am concerned it's almost ready - I'd only ask for spkg-install printing something meaningul.

This would need info whether the package is involved in building the binary distribution.

comment:11

I don't think our binary builds ship TeX.

Stalled in needs_review or needs_info; likely won't make it into Sage 9.5.
