[FSDP] Remove module.wrapper_config support (#70340)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/70340
Some wrap APIs support module.wrapper_config to specify the FSDP
arguments, though this feature is currently unused in all use cases and there
is no plan to support this API. enable_wrap() and wrap() along with FSDP
constructor wrapping should be enough for all use cases, so get rid of the
unnecessary code.
