[HIPIFY][feature] Support for fp8 data types

[foreverlms]

Problem Description

Such as when I hipify a cu file having fp8 datatype in it, after the hipify-clang command, the fp8 datatype doesn't turned into HIP fp8 type.

For example:

__nv_fp8_e4m3

doesn't change and the hipify-clang will report error:

 error: unknown type name '__nv_fp8_e4m3'

Why? Doesn't hipify support FP8?

Hello @foreverlms,

Currently, HIP supports some of the fp8 data types and APIs. Whereas, HIPIFY tools don't. Thank you for pointing it out.

Marking the ticket as a feature to Implement.
