MDEV-23634: Select query hanged the server and leads to OOM ...bb-10.4-mdev23634
Handle "col<>const" in the same way that MDEV-21958 did for "col NOT IN(const-list)": do not use the condition for range/index_merge accesses if there is a unique UNIQUE KEY(col). The testcase is in main/range.test. The rest of test updates are due to widespread use of 'pk<>1' in the testsuite. Changed the test to use different but equivalent forms of the conditions.
