add missing <stdint.h> to mfxparser.cpp

[trofi]

Without the change build fails on gcc-13 as:

MediaSDK/api/mfx_dispatch/linux/mfxparser.cpp: In function 'std::string MFX::printCodecId(mfxU32)':
MediaSDK/api/mfx_dispatch/linux/mfxparser.cpp:60:3: error: 'uint8_t' was not declared in this scope
   60 |   uint8_t* data = reinterpret_cast<uint8_t*>(&id);
      |   ^~~~~~~
