Add support for OpenHarmony

This PR adds support for [OpenHarmony](https://gitee.com/openharmony/docs/) targets:
- `aarch64-linux-ohos`
- `arm-linux-ohos`

Compiler team MCP: https://github.com/rust-lang/compiler-team/issues/568

OpenHarmony uses a fork of musl with minor modifications, so most of the code is shared with other musl targets. Additionally, although OpenHarmony uses musl 1.2, it is still ABI-compatible with musl 1.1 so the existing bindings should continue to work until https://github.com/rust-lang/libc/pull/3068 is merged.

A PR to add the targets to rustc will follow after this is merged.
