Add command line option for separate debug info (#7178)
* Add command line option for separate debug info
Add command line arg -separate-debug-info which, if provided, produces
both a .spv and a .dbg.spv file. The .dbg.spv file contains full debug
info and the .spv file has all debug info stripped out.
Also add a DebugBuildIdentifier instruction to store a unique hash in
both the output files, so they can be more easily matched together.
A matching API is provided to allow using the Slang API to retrieve a
base and debug SPIRV as well as the debug build identifier string.
