register signal ops for opset 17 (#11778)
* Register signal ops for op set 17
Note code is mostly being moved, not added. These ops were previously
only registered as Microsoft contrib ops and only built if
`BUILD_MS_EXPERIMENTAL_OPS=1`. They've been added to the ai.onnx
standard op set in version 17.
Main components of this change:
* Move the kernels from the conrib_ops directory to the
core directory.
* Add function bodies for ms experimental ops. This will allow
old models that use the contrib ops to continue to function.
All the function bodies consist of a single op (the
new standard op), so performance overhead should be minimal.
Minor clean-up also in this change:
* De-duplicate get_scalar_value_from_tensor: put it in a new utils.h.
* Fix some bugs that caused compilation errors with the experimental
ops. Tested with `build.sh --ms_experimental`
* Fix some spelling errors and lint violations.
* Replace a couple of switch statements with `MLTypeCallDispatcher`.
* Use `InlineVector` instead of `std::vector`.
