Reduce resource utilization in TestHiveIntegrationSmokeTest

[ZacBlanco]

Description

1. use tiny schema instead of SF1 except where necessary
2. Increase JVM size to 5g

Goal is to reduce test flakiness and speed up runtime. This cut the average runtime by about 2-3 minutes on my M1 mac and decreased the maximum observed memory usage from ~3.7g to ~3.0g. The maximum usage depends on the tests which are running, but generally it is when two of the following are executing:

• testGroupedExecution
• testMaterializedPartitioning
• testPartialMergePushdown
• testWriteSortedTable
• testWritePreferredOrderingTable

Related to #24775
