meson: add docs, docs_pdf options

Browse Source 
Detect and report if the tools necessary to build documentation are available
during configure. This is represented as two new options 'docs' and
'docs_pdf', both defaulting to 'auto'.

This should also fix a meson error about the installdocs target, when none of
the doc tools are found.
