[lldb] Prioritize the MAKE_NO_DEBUG_INFO flag (#198801)
Some tests require an executable with no debug information. When
`lldb-dotest` is run with `--dwarf-version`, that flag currently takes
precedence over the debug info type specified in the test. This is
incorrect when the test explicitly expects the executable to have no
debug information.
Ensure `MAKE_NO_DEBUG_INFO` takes priority over `--dwarf-version` so
that tests requiring stripped executables behave correctly regardless of
how the test suite is invoked.
