Profiler bug-fixes and improvements (#482)

Summary:
Pull Request resolved: #482

Made the following changes to the profiler code -
- The parameter calculation skipped parameters defined in modules, and had unnecessary complexity - updated the logic
- `AdaptiveAvgPool2d` handles a single number `output_size` as well
- Added FLOPs for the `Identity` module
- Added support to specify an `activations` function to fetch activations from (similar to the `flops` function)
- Replaced the hacky list append logic with a class, `_ComplexityComputer`
- Implemented test cases which verify that the fixes work
