fresnel-fourier iter5b Phase 6 commit A: NEW src/codec.{h,c} — pixelformat_for_profile helper

Add a small helper that maps a VAProfile to its V4L2 OUTPUT-side pixel format FOURCC. Single source of truth, mirrors the per-profile probes in config.c::RequestQueryConfigProfiles (lines 138-188). Used by commits B + C in this series: - commit B: populate object_config->pixelformat at CreateConfig - commit C: surface.c reads the populated field to set OUTPUT format per-profile instead of hardcoded H264_SLICE Register in meson.build sources + headers.
