Subject: [PATCH 2/2] Guard x86 feature detection macro in pystrref/object.rs

The std::is_x86_feature_detected! macro only works on x86/x86_64
targets. This patch wraps the feature detection and AVX-512 code path
with cfg guards to allow compilation on non-x86 architectures.

On non-x86 targets, the code will fall through to the generic
implementation instead of attempting AVX-512 optimizations.

Upstream-Status: Inappropriate [Rejected by upstream https://github.com/ijl/orjson/pull/609]
