This commit adds support for parsing new .kernel_arg_metadata zeInfo's section,
which will be parsed only on demand (it won't get parsed on initial
zeInfo parsing).
Usage of populated structs will be added in the next commit.
Implemented section's parsing, decoding & populating corresponding fields in
kernelDescriptor.
