  [FuncSpec] Improve accounting of specialization codesize growth (#113448)

Only accumulate the codesize increase of functions that are actually
specialized, rather than for every candidate specialization that we
analyse.

This fixes a subtle bug where prior analysis of candidate
specializations that were deemed unprofitable could prevent subsequent
profitable candidates from being recognised.
