cmd/compile, cmd/link: record compiler flags in DW_AT_producer
This adds a whitelisted subset of compiler flags to the DW_AT_producer
DWARF attribute of each package compilation unit DIE. This is common
practice in DWARF and can help debuggers determine the quality of the
produced debugging information.
Fixes #22168.
