[jdk25u-dev] RFR: 8367278: Test compiler/startup/StartupOutput.java timed out after completion on Windows

[Roland Mesde]

This a multi-commit backport for Oracle JDK parity. The commits modify the same single test file.

JDK-8367278: Test compiler/startup/StartupOutput.java timed out after completion on Windows.

Reduces test iterations from 200 to 50 VM runs with randomly generated near-minimum code cache sizes. This maintains adequate test coverage while ensuring execution completes within the timeout limit, avoiding the need to increase the timeout value.

JDK-8358756: [s390x] Test StartupOutput.java crash due to CodeCache size.

This fix increases the initial code cache size to ensure adequate space for interpreter mode execution.

Please note that I am unable to run a validation test on the s390x platform due to unavailable hardware. Ran the specific test on linux-x64, linux-aarch64, macos-aarch64 and windows-x64:

(Passed) - make test TEST=test/hotspot/jtreg/compiler/startup/StartupOutput.java
