Vladislav Vaintroub 061adae9a2 MDEV-16944 Fix file sharing issues on Windows in mysqltest
On Windows systems, occurrences of ERROR_SHARING_VIOLATION due to
conflicting share modes between processes accessing the same file can
result in CreateFile failures.

mysys' my_open() already incorporates a workaround by implementing
wait/retry logic on Windows.

But this does not help if files are opened using shell redirection like
mysqltest traditionally did it, i.e via

--echo exec "some text" > output_file

In such cases, it is cmd.exe, that opens the output_file, and it
won't do any sharing-violation retries.

This commit addresses the issue by introducing a new built-in command,
'write_line', in mysqltest. This new command serves as a brief alternative
to 'write_file', with a single line output, that also resolves variables
like "exec" would.

Internally, this command will use my_open(), and therefore retry-on-error
logic.

Hopefully this will eliminate the very sporadic "can't open file because
it is used by another process" error on CI.

# Bug#60196 - Setting lowercase_table_names to 2 on Windows causing
# Foreign Key problems after an engine is restarted.
# This test case needs InnoDB, a lowercase file system,
# lower-case-table-names=2, and cannot use the embedded server
# because it restarts the server.
