SwiftPM will compute a hash of the arguments passed to `swift build`, `swift test`, etc to determine if a full rebuild is necessary. Currently, it doesn't take in to account whether `.doesNotAffectIncrementalBuild` is set on swift compiler options and so any time any compiler option changes it will perform a full rebuild. Expose the function that swift-driver uses to compute the argument hash which takes in to account `.doesNotAffectIncrementalBuild` so that SwiftPM can leverage it to reduce unnecessary rebuilds. In order to keep `BuildRecordInfo` hidden behind `_spi` the function was moved out to the standalone `BuildRecordArguments` struct.

This is required by SwiftPM's release/6.2 branch, which builds with swift-driver's release/6.2 branch. |

@swift-ci please test |
