[Docs] Add precision support reference page

[adeljo-amd]

Motivation

The goal of this PR is to standardize the precision support reference page format across all components, while also reducing the maintenance of burden of having to manually update the YAML data file in https://rocm.docs.amd.com/en/latest/reference/precision-support.html

Technical Details

• Each component maintains its own YAML file which will be eventually used in https://rocm.docs.amd.com/en/latest/reference/precision-support.html
• A new precision support reference page is introduced which will not override existing data type/precision support content; it will serve as the overview/summary that will be linked in the ROCm reference page

What is causing the "partial support" for int8 ?

[adeljo-amd]

This is something that was taken from https://rocm.docs.amd.com/en/latest/reference/precision-support.html?model=migraphx that was approved when it was made - is it not right? int8 is listed in shape.hpp; should it be full support instead?

What exactly do we mean by:

while also reducing the maintenance of burden of having to manually update the YAML data file in https://rocm.docs.amd.com/en/latest/reference/precision-support.html

It looks like the MIGraphX team needs to manually update this yaml file?

[adeljo-amd]

This PR aims to bring that yaml file over to this repo, so you just need to update it here. In the future, that page on the ROCm docs will automatically pull the yaml files from various repos, so there won't be a need to manually update it in the ROCm repo anymore.

Missing that we support the OCP MXFP4 (E2M1) datatype.

And to clarify, int8 should be changed to "full support"?
