bbbaa0ab - [Explicit Module Builds] Serialize --target= flag instead of -triple (#71987)

[Explicit Module Builds] Serialize --target= flag instead of -triple (#71987) Serialize a `--target=` flag (a driver option) instead of `-triple` (a frontend option). The `XCC` values are passed as driver flags, where `-triple` is not defined. The target is passed as a joined flag and value, which is more convenient for lldb to consume.
