- Move FLAGS_quiet definition from cli_main.cc to flags.cc (shared flags location)
- Change FLAGS_quiet in cli_main.cc to ABSL_DECLARE_FLAG (declaration only)
- Rename emu_test.cc FLAGS_rom to FLAGS_emu_test_rom to avoid conflict with shared FLAGS_rom
- Update usage message in emu_test.cc to reflect renamed flag
This fixes multiple definition errors on Linux where FLAGS symbols were defined
in multiple translation units. FLAGS_quiet is now defined once in flags.cc and
declared where needed. The emulator test now uses unique flag names.
Fixes symbol conflicts identified in Windows build handoff analysis.
