🐛 Add extra clang flags to compiliation database
🐛 Add extra clang flags to compiliation database

Summary:
- Added "-target armv7a-none-none-eabi" to compilation database to help
  cquery figure out how we're compiling
- Explicitly mention "-fno-ms-compatibility" and friends for Windows
  because cquery insists on including them and we don't want them when
  crossing compiling. This may be a bug in upstream cquery (where
  extraClangArguments isn't being included properly when indexing)

Test Plan: [X] Cquery gives fewer false errors
