YARN-11704. No need to apply extra 'AND' placement constraint for non tags in PlacementConstraintManager.getMultilevelConstraint

[zuston]

Description of PR

After applying the placement constraint allocator in our internal cluster, I found some hotpoint that will effect the scheduling performance as the allocation time metric value increase a lot.

After dumping the flamegraph, the hotpoint is that the SingleConstraintAppPlacementAllocator.checkCardinalityAndPending, this should be optimized by like cache or other ways. But the unnecessary nested AND placement constraint may be a small improvement for this case.

How was this patch tested?

For code changes:

• Does the title or this PR starts with the corresponding JIRA issue id (e.g. 'HADOOP-17799. Your PR title ...')?
• Object storage: have the integration tests been executed and the endpoint declared according to the connector-specific documentation?
• If adding new dependencies to the code, are these dependencies licensed in a way that is compatible for inclusion under ASF 2.0?
• If applicable, have you updated the LICENSE, LICENSE-binary, NOTICE-binary files?

PTAL @slfan1989 This is a small improvement for placement constraint mechanism
