Convert remaining template_preprocess functions in module include files

Just three modules left, with 5 template preprocess functions in total. One less than I expected, also because block_content is being taken care of in a separate issue and fully deprecated.

Seems like a good conversion

+1

Did all of my usual checks except the zebra check.

No double _
All deprecations are the right version and the same 11.3 and removed in 12.

All functions are __FUNCTION__ and files are __FILE__

initial preprocess align and so do the deprecated calls.

Comments were updated correctly.

I'll run the zebra check if i get a chance.

Committed/pushed to 11.x, thanks!
