For certain network topologies, MCR could hang.
This patch fixes that case.

* [KERAS]upsampling3d and zeropadding3d op

* [KERAS]upsampling3d and zeropadding3d test case

* Review comments updated

- Support vectorized casts

- It is incorrect to extract elements from int8x4 with

   0x000000ff & (x >> i * 8)

  as this value is of type int in C/C++. If this expression
  is used for sign extensions, the sign bit will be wrong.
  Simply use C style casts instead and sign bits will just work.

Rationale: The current hybrid module is more aligned with the te part.
We might consider add a new varient of hybrid script that support the unified IR later.
This refactor paves for the potential later changes.

- Reduce CI docs task log size.
- Update the relation to halide to the latest state.

* [PYTORCH]AvgPool3d, MaxPool3d and Squeeze op support

* Testcases added

* review comments

- Migrate LowerTVMBultin
- Migrate inferFragment, LowerThreadAllreduce
- Migrate ThreadSync
- Refactor target::Build to directly take IRModule.
- Remove un-used legacy functions.
