Introduce MCAsmInfo::UsesSetToEquateSymbol and prefer = to .set
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.
