This reverts commit 7d5640b9.

[example] check dreambooth example gradient accmulation must be 1

* [fx] allow control of ckpt_codegen init

Currently in ColoGraphModule, ActivationCheckpointCodeGen will be set automatically in __init__. But other codegen can't be set if so. 
So I add an arg to control whether to set ActivationCheckpointCodeGen in __init__.

* code style

support full evoformer tracer, which is a main module of alphafold. previously we just support a simplifed version of it.
1. support some evoformer's op in fx
2. support evoformer test
3. add repos for test code
