YuLi daaa74a72e fix(ext-codec): harden H264/H265 SPS/VPS parsing against malformed input (#4781) ...

- Add 1MiB cap on parameter set size to prevent memory exhaustion
- Validate SPS/VPS field ranges per H.264/H.265 spec (sps_id, bit_depth, poc_type, ref_frames, etc.)
- Fix Exp-Golomb reader EOF/overflow handling (throw instead of silent zero)
- Use wide integers for crop/delta_scale arithmetic to prevent overflow
- Commit output params only after full parse success (no partial metadata)
- Harden getExtraData with size checks, from_nalu API, AssertFailedException guard
- Avoid redundant update() in inputFrame_l (retry only on SPS change or first-ready)
