`AddressLowering` was a module transform because it needed to advance the SIL stage flag for all functions at once, via a module-wide `loweredAddresses` bit on `SILModule`. Replace that bit with a per-function `HasLoweredAddresses` flag: `AddressLowering` now runs on one function at a time, sets the flag after lowering, and returns early if the flag is already set. Add `SILModuleConventions` factory methods (`forFunction`, `forBuildModeDefault`, `withLoweredAddresses`, `forFunctionWithOverride`) so every construction site threads the function's own lowered state rather than reading the module flag. `SILFunction::getLoweredType` and related type-lowering entry points gain a `loweredAddresses` parameter for the same reason.
