BRT: Fix ZAP entry endianness
During original block cloning implementation a mistake was made,
making BRT ZAP entries an array of 8 1-byte entries instead of 1
entry of 8 bytes. This makes the pools non-endian-safe.

This commit introduces a new read-compatible pool feature
"com.truenas:block_cloning_endian", fixing the endianness issue
for new pools while maintaining compatibility with existing ones.

The feature is automatically activated when creating the first BRT
ZAP (ensuring we don't activate it on pools that already have BRT
entries in the old format).  When active, BRT entries are stored
as single 8-byte values.
