[SPARK-34700][SQL] SessionCatalog's temporary view related APIs should take/return more concrete types

[imback82]

What changes were proposed in this pull request?

Now that all the temporary views are wrapped with TemporaryViewRelation(#31273, #31652, and #31825), this PR proposes to update SessionCatalog's APIs for temporary views to take or return more concrete types.

APIs that will take TemporaryViewRelation instead of LogicalPlan:

createTempView, createGlobalTempView, alterTempViewDefinition

APIs that will return TemporaryViewRelation instead of LogicalPlan:

getRawTempView, getRawGlobalTempView

APIs that will return View instead of LogicalPlan:

getTempView, getGlobalTempView, lookupTempView

Why are the changes needed?

Internal refactoring to work with more concrete types.

Does this PR introduce any user-facing change?

No, this is internal refactoring.

How was this patch tested?

Updated existing tests affected by the refactoring.

This is only called from SparkGetColumnsOperation.scala and now that a raw temp plan always has CatalogTable, the caller can just directly get the schema from the raw plan, and I don't see a reason to expose this as a def. Check SparkGetColumnsOperation.scala changes below.
