752adc36 - [clang][Darwin] Simplify deployment version assignment in the Driver (#142013)

[clang][Darwin] Simplify deployment version assignment in the Driver (#142013) To be able to handle all of the ways the platform & deployment version can be represented in command line flags, the Darwin toolchain holds a type `DarwinPlatform` to help represent them. This patch simplifies the logic by: * reducing the amount of work done between string & version tuples conversions * renaming variables to reduce confusion about what target triple information is being manipulated. * allowing implicit transformation of macOS10.16 -> 11, there are other places in the compiler where this happens, and it was a bit confusing that the driver didn't do that for the cc1 call. This is not a major refactor, but more simple & common tweaks across the file, in hopes to make it more readable.
