soc/intel/meteorlake: Change VBOOT_HASH_BLOCK_SIZE to 4 KiB
Default VBOOT_HASH_BLOCK_SIZE is 1 KiB and increasing it to 4 KiB
helps in improving overall boot time since it reduces hashing and
body loading time (~30ms).
Backport changes from commit hash 84532dae1 (soc/intel/alderlake:
Change VBOOT_HASH_BLOCK_SIZE to 4 KiB).
