RFR: 8302146: Move TestOverloadCompileQueues.java to tier3

Fri Feb 17 16:13:51 UTC 2023

This test is expected to run long, as it has to fill the compile queue. But it does not need to run at a low tier. We just want to run it occasionally.

Moved it to `tier3`, by adding it to `hotspot_slow_compiler`, which is excluded from `tier1` and `tier2`.
