Introduce float 8 types (#14731)
### Description
The PR implements FloatE4M3FN, FloatE5M2, FloatE4MEFNUZ, FloatE5M2FNUZ
as described in PR https://github.com/onnx/onnx/pull/4805. It uses CUDA
API to cast float/half to float8 if CUDA>=11.8, a custom implementation
if CUDA<11.8.

* It implements, Cast, QuantizeLinear, DequantizeLinear for all types on
CPU, only for types FloatE4M3FN, FloatE5M2 on CUDA.
* It extends the supported types for control flow operator, Shape,
Reshape, Identity, If, Loop, Scan, Reshape
* It implements Equal(19).
* Cast, QuantizeLinear, DequantizeLinear operators now support a
parameter `saturate` only valid for float 8 types. It is true by
default. In that case, any value out of range is converted into the
maximum float 8 value. If false, it is infinite.
* QuantizeLinear, DequantizeLinear now supports multiple scales on CUDA
(and ROCm by extension), scale = 1D tensor with one scale per channel

### Motivation and Context
Supports latest onnx version.

ORT Format File

This directory contains the generated ts file necessary to support the ORT file format. The file is generated from the ORT file format schema. Please do not directly modify the generated ts header file.

The ORT file format schema uses FlatBuffers serialization library. To update its generated ts file,

  1. Download or locate the ort.fbs file.
  2. Download FlatBuffers compiler: Download the latest flatc tool (flatc_windows.zip) from Flatbuffers Release Page. Unzip and run

> flatc_windows.exe --ts <path to ort.fbs>

This should result in ort-generated.ts being updated.
