Cherry-pick of #81850
Explanation: The Swift dependency scanner collects diagnostics as it performs a scan, including those emitted by the integrated Clang dependency scanner. Such diagnostics are then presented to the client, most-likely the
swift-driveror another build system. This change adds such diagnostic handling to those emitted by the clang dependency scanner when scanning the bridging header file.Scope: Specifically dependency scanning actions (as part of a build with explicitly-built modules) which involve scanning a bridging header file and emitting diagnostics during said header scan.
Risk: Low, the code-path this changes affects only how Clang scanner-emitted diagnostics are handled by collecting them into the scanner's diagnostic handler, like any other diagnostics, instead of just dumping them to stderr.
