Because they all have C-like syntax, so they have the same setup for indenting 
and filling block comments, for example.

c-ts-common.el sounds good to me.

I’d prefer c-ts-common.el over treesit.el, since they only apply to C-like 
languages. There is no harm putting them in a separate file, right? I wrote 
some commentary in c-ts-mode, which notes all the shared functions and 
variables.
