FBTF: Move individual XXXMsg_Params structs to a new file.

The new file, render_messages_params.h, is included in 57 files, while
render_messages.h is included in 176 files. Moving the Params structs to their
own file allow pruning the included headers.

(Part 2 of this cleanup will be sorting the individual structs into themes
to further minimize header inclusion.)
