Enable manpages wherever possible; drop SGML stack

This patchset eanbles (conditional) building of manpages in various recipes; there's plenty more recipes where manpages are supplied pre-built, for them nothing needs to be done. These changes enable better support for API documentation in Yocto SDKs (https://bugzilla.yoctoproject.org/show_bug.cgi?id=8584).

Bonus feature: the entire SGML stack is removed from OE-Core. It has become basically obsolete, and not needed by anything in either OE-Core or broader meta-oe collection of layers. If you need it in your 3rd party layer, please create meta-sgml.

V2 of the patch adds fixes for lttng-tools dependency issue (unrelated to manpages, but uncovered by enabling them). Also documentation packages are now added to SDK images.

The following changes since commit e5815d0b607ff262663864d51fe51fbb37172329:
