[MDEV-35796] OPT_PAGE_CHECKSUM is ignored if innodb_encrypt_log=ON - Jira

Description

In the merge of the ~~MDEV-18976~~ implementation, a logical conflict with ~~MDEV-14425~~ was resolved incorrectly. The log record parser is reading the contents of an OPTION record without attempting to decrypt it. Unless the first payload octet OPT_PAGE_CHECKSUM happens to encrypt to itself, these record will be ignored. By design, all OPTION records can be ignored without breaking anything.

In debug-instrumented builds, InnoDB is writing OPT_PAGE_CHECKSUM records so that some recovery errors can be caught better. This bug causes that to be mostly a wasted effort when innodb_encrypt_log=ON.
