WL#9027 : Remove usage of skip from tests(except rpl and binlog) that need specific mysqld options to run

Description:
============

The objective of the work-log is to eliminate the dependency of "inc" files from
the test-cases which is being used for passing mysqld server options. Under this
work-log, all inc files in each MTR suites (except replication and binlog) are
analyzed. Also, all the redundant inc files are cleaned up as part of this WL.

Fix:
====
1. The fix involves deleting all the inc files which are not being used by any test.
2. The fix involves using mysqld global server variables to be passed from within the
   test or through an opt file eliminating the dependency on the inc file.
