[lworld] RFR: 8376883: [lworld] Only enable compiler/valhalla/inlinetypes/TestTrivialMethods.java for aarch64 and x86

[Fei Yang]

Hi,

Please consider this small test-only change.
Seems this test depends on the two optimizations: -XX:+InlineTypePassFieldsAsArgs and -XX:-InlineTypeReturnedAsFields.
It fails without either of them. So it might be more reasonable to only enable it for platforms which implement these
two optimizations.

Verified on linux-aarch64 platform.
