media: hantro: Avoid global variable for jpeg quantization tables
On a system with multiple encoders present, it's possible for two
encoders to write to the global luma and chroma quantization tables at
the same time if they both submit a JPEG frame to be encoded. Avoid
this race by moving the tables into the `jpeg_ctx` structure which is
stored on the stack.
