Use %env_asan_opts= substitution instead of 'env ASAN_OPTIONS=$ASAN_OPTIONS'

Summary: The lit internal shell is used by default on Windows, and it does not support bash variable expansion. Because bash variable expansion interacts with tokenization, it is prohibitively difficult to make the existing lit shell do general shell variable expansion. The most common use of shell variables in the asan tests is to add options to the default set of options set by lit.cfg. We can avoid the need for variable expansion with a substitution that expands to 'env ASAN_OPTIONS=<defaults:>'. This has the side benefit of shortening the RUN lines, so it seemed better than implementing limited variable expansion in lit.
