avcodec/jpegxl_parser: add some icc profile checks
This patch will cause the parser to abort if it detects an icc profile
with an invalid size. This is particularly important if the icc profile
is entropy-encoded with zero bits per symbol, as it can prevent a
seemingly infinite loop during parsing.
Fixes: infinite loop
