… more scenarios such as PartitioningCollection
### What changes were proposed in this pull request?
This PR proposes to improve `EnsureRquirement.reorderJoinKeys` to handle the following scenarios:
1. If the keys cannot be reordered to match the left-side `HashPartitioning`, consider the right-side `HashPartitioning`.
2. Handle `PartitioningCollection`, which may contain `HashPartitioning`
### Why are the changes needed?
1. For the scenario 1), the current behavior matches either the left-side `HashPartitioning` or the right-side `HashPartitioning`. This means that if both sides are `HashPartitioning`, it will try to match only the left side.
The following will not consider the right-side `HashPartitioning`:
```
val df1 = (0 until 10).map(i => (i % 5, i % 13)).toDF("i1", "j1")
val df2 = (0 until 10).map(i => (i % 7, i % 11)).toDF("i2", "j2")
df1.write.format("parquet").bucketBy(4, "i1", "j1").saveAsTable("t1")df2.write.format("parquet").bucketBy(4, "i2", "j2").saveAsTable("t2")
val t1 = spark.table("t1")
val t2 = spark.table("t2")
val join = t1.join(t2, t1("i1") === t2("j2") && t1("i1") === t2("i2"))
join.explain

2. For the scenario 2), the current behavior does not handle `PartitioningCollection`:
```
val df1 = (0 until 100).map(i => (i % 5, i % 13)).toDF("i1", "j1")
val df2 = (0 until 100).map(i => (i % 7, i % 11)).toDF("i2", "j2")
val df3 = (0 until 100).map(i => (i % 5, i % 13)).toDF("i3", "j3")
val join = df1.join(df2, df1("i1") === df2("i2") && df1("j1") === df2("j2")) // PartitioningCollection
