Use aarch64/AArch64 consistently over arm64/ARM64

* The correct name is AArch64 and arm64 is too visually similar to amd64.

 * `foreign_object.to_s` now uses `InteropLibrary#toDisplayString()` (and still `asString()` if `isString()`).
 * `foreign_object.inspect` has been improved to be more useful (include the language and meta object).
 * `foreign_object.class` now calls `getMetaObject()` (except for Java classes, same as before).
-* Add basic support for Linux ARM64.
+* Add basic support for Linux AArch64.
 * `foreign_object.name = value` will now call `Interoplibrary#writeMember("name", value)` instead of `invokeMember("name=", value)`.
 * Always show the Ruby core library files in backtraces (#1414).
 * The Java stacktrace is now shown when sending SIGQUIT to the process, also on TruffleRuby Native, see [Debugging](doc/user/debugging.md) for details (#2041).

+* AArch64 (aka `arm64`): Supported on Linux (from 21.2) and on macOS (from 22.2)
 
 You may find that TruffleRuby will not work if you severely restrict the
 environment, for example, by unmounting system filesystems such as `/dev/shm`.
