java.nio.Bits.unaligned() return false for ARM architecture

[davidshtian]

Describe the bug

During the usage, a issue was encountered caused by java.nio.Bits.unaligned(). This attribute only returns true for i386|x86|amd64|x86_64|ppc64|ppc64le architecture, but not for aarch64, the issue was also described in java.nio.Bits.unaligned() doesn't handle aarch64. While AdoptOpenJDK has fixed the issue (like jdk8u191-b12 and later versions) with patches, make it return true for aarch64.

To Reproduce

As shown in the source code in Corretto 8.252.09.1:
https://github.com/corretto/corretto-8/blob/release-8.252.09.1/src/jdk/src/share/classes/java/nio/Bits.java

Expected behavior

Return true for aarch64 in java.nio.Bits.unaligned()
