Subject: [PATCH] feat: enable loongarch64 LSX SIMD feature gate

The loongarch64 LSX SIMD code already exists in
src/binary16/arch/loongarch64.rs and is properly gated behind
cfg(target_arch = "loongarch64"), but building on loongarch64
with nightly Rust fails because the crate root is missing:

  #![feature(stdarch_loongarch)]

Without this, core::arch::loongarch64 intrinsics raise E0658 even
on nightly, since stdarch_loongarch is still an unstable feature
(Rust issue #117427).
