Add RDNA3 BUFFER_ATOMIC_ADD_F32 -> interlockedAddf32 support (and all the fp32 atomics)

[Bloodwyn]

Dear AMD folks,

It has been quite some time since the release of the RDNA3 architecture, which has support for atomic floating-point instructions.
So far, they are only exposed to other APIs such as Vulkan, but NOT to DirectX, which is a shame!

NVIDIA has been supporting it for several in years in their extension - so please also add it.

Cheers
