[Misc] Revert current aarch64 support
Browse files Browse the repository at this point in the history 
Summary: OpenJDK8u mainline has aarch64 support since 292, and this conflicts with current aarch64 support in Dragonwell8.
Need to revert current aarch64 support, to prepare further merge with 8u292

Test Plan: existing x86 tests

Reviewed-by: zhengxiaolinX, joeyleeeeeee97, ziyilin, kuaiwei
