ISSUE:       https://github.com/FirebirdSQL/firebird/issues/8230
TITLE:       Ability to obtain PID of server process for current connection without querying mon$ tables
DESCRIPTION:
    Test verifies ability to call appropriate rdb$get_context() and compare its value with 
    mon$attachments.mon$server_pid. They must be equal (and no error must raise).
NOTES:
    [29.10.2024] pzotov
    Checked on 6.0.0.511-781e5d9 (intermediate build).
