  [DebugInfo] Add option for producing no source-file hash (#148657)

Clang can chose which sort of source-file hash is attached to a DIFile
metadata node. However, whenever hashing is possible, we /always/ attach
a hash. This patch permits users who want DWARF5 but don't want the file
hashes to opt out, by adding a "none" option to the -gsrc-hash option
that skips hash computation.
