 Apply SplitSections to all C compilations

 Previously this was added only to the RTS's C files (those are the bulk
 of it though), but there are C bits in ghc-prim, integer-gmp and base
 too.

 Followup for #8405, allows the large table of character properties in
 base to be stripped when not used.

 Test Plan: validate
