Enable full tools and profiler for dist-loongarch64-{linux,musl}

When the LoongArch targets were first introduced, the LLVM support was
still immature and various tools were not supported on LoongArch.
Nowadays most infra is in place, so it is time to enable them on
LoongArch to provide a better experience for users of these targets.
Plus, the profiler support is needed by Chromium, so better provide it
in the official artifacts.
