Added/Updated tests\bugs\core_5118_test.py: Replaced test query so that it does not use index navigation ('plan order') but still checks indexed access. Requested by dimitr, letters with subj 'core_5118_test', since 11.09.2024 17:26. Checked on 6.0.0.452, 5.0.2.1493, 4.0.5.3136, 3.0.13.33789

DESCRIPTION:
JIRA: CORE-5118
FBTEST: bugs.core_5118
NOTES:
[12.09.2024] pzotov
Replaced test query so that it does not use index navigation ('plan order') but still checks indexed access.
Three separate queries with 'PLAN ... INDEX' are used instead of one with 'where <comp_field> IN <literals_list>'.
This is because of optimizer changed in 5.x and issues plan with only *one* occurrence of 'INDEX' for such cases.
See: https://github.com/FirebirdSQL/firebird/pull/7707 - "Better processing and optimization if IN <list>".
