Summary:
Sub-step of my attempt to split up the torch_cuda library, as it is huge. Please look at https://github.com/pytorch/pytorch/issues/49050 for details on the split and which files are in which target.
This PR introduces two new macros for Windows DLL purposes, TORCH_CUDA_CPP_API and TORCH_CUDA_CU_API. Both are defined as TORCH_CUDA_API for the time being.

Summary:
1. Added CudaFusionGuard as the custom TypeCheck for nvfuser; enabled dynamic shape support with profiling executor;
2. dropped support for legacy fuser;
3. re-enabled nvfuser tests;
4. added registration for profiling record to allow profiling on user specified nodes.

Summary:
A lot of changes are in this update, some highlights:
- Added Doxygen config file
- Split the fusion IR (higher level TE like IR) from kernel IR (lower level CUDA like IR)
- Improved latency with dynamic shape handling for the fusion logic
- Prevent recompilation for pointwise + reduction fusions when not needed
- Improvements to inner dimension reduction performance
- Added input -> kernel + kernel launch parameters cache, added eviction policy
- Added reduction fusions with multiple outputs (still single reduction stage)
- Fixed code generation bugs for symbolic tiled GEMM example
- Added thread predicates to prevent shared memory form being loaded multiple times
- Improved sync threads placements with shared memory and removed read before write race
- Fixes to FP16 reduction fusions where output would come back as FP32

Summary:
Had a bunch of merged commits that shouldn't have been there, reverted them to prevent conflicts. Lots of new features, highlights listed below.
**Overall:**
- Enables pointwise fusion, single (but N-D) broadcast -- pointwise fusion, single (but N-D) broadcast -- pointwise -- single (but N-D) reduction fusion.
**Integration:**
- Separate "magic scheduler" logic that takes a fusion and generates code generator schedule
- Reduction fusion scheduling with heuristics closely matching eagermode (unrolling supported, but no vectorize support)
- 2-Stage caching mechanism, one on contiguity, device, type, and operations, the other one is input size->reduction heuristic
**Code Generation:**
- More generic support in code generation for computeAt
- Full rework of loop nest generation and Indexing to more generically handle broadcast operations
- Code generator has automatic kernel launch configuration (including automatic allocation of grid reduction buffers)
- Symbolic (runtime) tilling on grid/block dimensions is supported
- Simplified index generation based on user-defined input contiguity
- Automatic broadcast support (similar to numpy/pytorch semantics)
- Support for compile time constant shared memory buffers
- Parallelized broadcast support (i.e. block reduction -> block broadcast support)
