RFR: 8366941: Excessive logging in serviceability tests causes timeout

[Ioi Lam]

These tests use `-Xlog:all=trace` which can cause excessive output that runs very slowly, especially on Windows.
A recent change, [JDK-8362566](https://bugs.openjdk.org/browse/JDK-8362566), adds lots of output to `-Xlog:aot+map*=trace`. As a result, some of these tests are starting to timeout.

None of these tests actually require a lot of logging output. The should be fixed to use `-Xlog:all=info` instead.
