Commit b5615eff0d00 introduced comment in result file during shutdown.
In case of Windows for the tests involving `file_key_managment.so` as plugin-load-add the tests will be overwritten with .dll extension.
The same happens with environment variable `$FILE_KEY_MANAGMENT_SO`.
So the patch is removing the extension to be extension agnostic.

Also fixes MDEV-23929: innodb_flush_neighbors is not being ignored
for system tablespace on SSD
When the maximum configured number of file is exceeded, InnoDB will
close data files. We used to maintain a fil_system.LRU list and
a counter fil_node_t::n_pending to achieve this, at the huge cost
of multiple fil_system.mutex operations per I/O operation.
fil_node_open_file_low(): Implement a FIFO replacement policy:
The last opened file will be moved to the end of fil_system.space_list,
and files will be closed from the start of the list. However, we will
not move tablespaces in fil_system.space_list while
i_s_tablespaces_encryption_fill_table() is executing
(producing output for INFORMATION_SCHEMA.INNODB_TABLESPACES_ENCRYPTION)
because it may cause information of some tablespaces to go missing.
We also avoid this in mariabackup --backup because datafiles_iter_next()
assumes that the ordering is not changed.
IORequest: Fold more parameters to IORequest::type.
fil_space_t::io(): Replaces fil_io().
fil_space_t::flush(): Replaces fil_flush().
OS_AIO_IBUF: Remove. We will always issue synchronous reads of the
change buffer pages in buf_read_page_low().
We will always ignore some errors for background reads.
This should reduce fil_system.mutex contention a little.
fil_node_t::complete_write(): Replaces fil_node_t::complete_io().
On both read and write completion, fil_space_t::release_for_io()
will have to be called.
fil_space_t::io(): Do not acquire fil_system.mutex in the normal
code path.
xb_delta_open_matching_space(): Do not try to open the system tablespace
which was already opened. This fixes a file sharing violation in
mariabackup --prepare --incremental.

Problem was that key rotation from encrypted to unecrypted was skipped
when encryption is disabled (i.e. set global innodb-encrypt-tables=OFF).
fil_crypt_needs_rotation
If encryption is disabled (i.e. innodb-encrypt-tables=off)
and there is tablespaces using default encryption (e.g.
system tablespace) that are still encrypted state we need
to rotate them from encrypted state to unencrypted state.
