Consolidate cc-specific cqueries.

There is little overlap at this point, but we expect these to converge
more over time, to handle exported includes, libs, etc., this will allow
those changes to be handled in one place and allow more consolidation of
code.

Test: bp2build generate & sync; mixed build libc
