Description

MDEV-39772: SET GLOBAL innodb_log_archive=OFF breaks recovery

log_t::set_recovered(): Set circular_recovery_from_sequence_bit_0 if the log was recovered in the innodb_log_archive=ON format, so that a subsequent SET GLOBAL innodb_log_archive=OFF will properly wait for a checkpoint before changing the format.

This fixes up #4405.

How can this PR be tested?

mysql-test/mtr --parallel=auto innodb.blob-crash

The innodb_page_size=4k and innodb_page_size=8k variants of that test would fail when the fix is absent.

Code Review

This pull request updates InnoDB's recovery logic in log0recv.cc by adjusting the circular_recovery_from_sequence_bit_0 condition to account for when innodb_log_archive is enabled. It also adds and refines corresponding test cases in the blob-crash and log_archive test suites to validate log archiving behavior during crashes and restarts. There are no review comments, so I have no feedback to provide.
