[jdk25u-dev] RFR: 8370646: TestLargeUTF8Length.java needs lots of memory

[Roland Mesde]

Backporting JDK-8370646: TestLargeUTF8Length.java needs lots of memory.

For parity with Oracle JDK. Fix adds minimum memory requirements for test. Ran GHA Sanity Checks (passed), jtreg tier1 tests (passed) and related tests (passed) on linux-x64, linux-aarch64, macos-aarch64 and windows-x64. Also ran a test on an EC2 instance (linux-x64) with less than the required memory (t2.large - 8 GB) and the test was not executed:

(Passed) - make test-tier1
(Passed) - make test TEST=test/hotspot/jtreg/runtime/jni/checked/TestLargeUTF8Length,java

Results are attached.
