Extend Balsara's tests to arbitrary directions.

[lwJi]

For the purpose of testing AMR boundary artifacts, we extend Balsara's test to arbitrary directions:

1. only the implementation of Balsara's test are modified, all the other modifications are made by clang-format,
2. the old parfile for Balsara's test should produce the exact same result as before.
3. it only support single rotation along axis
