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

[rm-gh-8]

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

For parity with Oracle JDK.

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. PR #106 depends on this PR.

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

Results are attached:

linux-aarch64-specific-test.log
linux-x64-specific-test.log
macos-aarch64-specific-test.log
windows-x64-specific-test.log

/approval request for backport of JDK-8358756: [s390x] Test StartupOutput.java crash due to CodeCache size.

For parity with Oracle JDK.

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

Low risk - fix addresses a crash, but requires validation on memory-constrained platforms to ensure the increased initial allocation doesn't cause resource issues.
