WL#13410 - Move testcases in sys_vars and funcs_1 suites that needs MyISAM to a separate .test file

    Description:
    There are tests in sys_vars and funcs_1 suites that have some testcases running on MyISAM.These are marked with have_myisam.inc and will be skipped on a server built without MyISAM.Currently MyISAM is always compiled in and hence these tests will run. This will change with the OCI offering where the plan is to support only Innodb.We do not want entire .test files to be skipped due to a few testcases that need MyISAM.

    This WL will move the sections that need MyISAM to a separate .test file.

    Solution:
    All myisam specific sub-tests have been moved out into seperate test-cases
