fix: point submodules to Provenance forks, skip Cores in CI checkout

Many submodules had local-only commits that CI couldn't fetch from
upstream remotes. Updated .gitmodules to use Provenance-Emu forks
for RetroArch and rcheevos.

CI workflow now skips all Cores/* submodules (they use pre-built
xcframeworks, not source compilation) and inits everything else
with --depth 1 for speed.
