RFR: 8350665: SIZE_FORMAT_HEX macro undefined in gtest

[SendaoYan]

Hi all,

SIZE_FORMAT_HEX macro undefined in test/hotspot/gtest/runtime/test_virtualMemoryTracker.cpp.
The SIZE_FORMAT_HEX macro should be replace as "0x%zx" instead.

Trivial fix, change has been verified locally, test-fix only, no risk.
