Introduce MCAsmInfo::UsesSetToEquateSymbol to control the preferred syntax for symbol equating. We now favor the more readable and common `symbol = expression` syntax over `.set`. This aligns with pre- https://reviews.llvm.org/D44256 behavior. On Apple platforms, this resolves a clang -S vs -c behavior difference (resolves #104623). For targets whose = support is unconfirmed, UsesSetToEquateSymbol is set to false. This also minimizes test updates. Pull Request: https://github.com/llvm/llvm-project/pull/142289
