JIT implementation of the gather operator
Added a few more unit tests to this one as well since I saw some odd behavior during bring up.

Improvements/Additions to be made:

changes for the quant_convolution,
changes for the deconvolution,
Macros for MIOpen status checks

* Remove unused headers

Updated each source file in the repo with the existing license.

Remove std references in runtime compilation since these are not available when using hiprtc and the headers may not be available on the system

Add ref and gpu implementations for ONNX op GatherND

Resolves #1032
