[Archermmt]

This is a pull request for MSC(Multi-System Compile)
RFC: https://discuss.tvm.apache.org/t/rfc-unity-msc-introduction-to-multi-system-compiler/15251/5
Tracking issue: #15233

This is the Milestone 5 for MSC: Add MSCWrapper as compression toolchain.
To limit each PR in reviewable size, the Milestone 5 will be split into some steps:
[M5.1] Build wrapper to support compression.
[M5.2] Enable quantize && prune with gym by wrapper.
[M5.3] Support torch.dynamo for dynamic models.

Gym for msc works like autotvm to tvm. Gym use environment to evaluate compression strategy and agent will search the best strategy.

This PR:

1. Refactor the gym system. The example of using gym for auto compression is: https://github.com/apache/tvm/blob/main/gallery/how_to/work_with_msc/using_tools.py, use python use_tools.py --prune --gym to test auto compression.
2. Refactor the register for MSC objects, so that custom tools can be register for optimize the model.
3. Enable export after run msc pipeline. The exported tar.gz package can be used for loading model
