Add ASTC support for PVRv3 textures and improve PVR format detection and safety.

  • Added mapping for PVRv3 ASTC_* formats in v3_pixel_formathash.
  • Implemented correct ASTC block size calculation in PVRv3 loader (bx/by → block count → dataSize).
  • Added software fallback to RGBA8 when ASTC hardware decoding is not supported.
  • Honored the PremultipliedAlpha flag in PVRv3 header.
  • Made isPvr() detection more robust by comparing header sizes instead of OR check.
  • Clarified BGRA8888 fallthrough and fixed RG8 assert message.
