Oleg Smirnov 893761b35c MDEV-37292 Hint NO_INDEX() disables all indexes if none of given index names is resolved ...

When a hint has a list of index names, for example,
  `NO_INDEX(t1 idx1, idx2)`
there is a possibility that some or all of the listed index names will
not be resolved. If none of them are resolved, the hint becomes a table-level
hint, for example, `NO_INDEX(t1)`, which erroneously disables all indexes
of `t1` instead of disabling only some of them.

This commit addresses this issue by adding an additional check: a hint
containing a list of index names is considered resolved only when at least one
of the listed names is resolved successfully.
