1b35b1a0 - Properly skip distributed tests when distributed module is not built (#52945)

Properly skip distributed tests when distributed module is not built (#52945) Summary: Currently there is some code that intends to skip distributed tests if the distributed module is not built. However, they are missing in some test files; and in some other test files they are checked after distributed module is imported, which leads to failure. This is generating a lot of headaches when testing minimal builds locally.
