Zero-init HIDL core types.
hidl_pointer - already zero initialized
hidl_string - now memset to 0
hidl_array - has no pad to initialize, default initialize since we
now expect structs to be default initialized to sane values.
hidl_vec - now memset to 0
hidl_memory - has three aligned(8) items which are always set
hidl_version - unused, but has two uint16_t entries
Since they are passed across processes.
