ROCm libraries with version <5 are cleaned up, remove version 4 support
for rocm.eclass.

RDNA3 has initial support in ROCm libraries starting from 5.4 releases.
Enable gfx110* amdgpu_targets in rocm.eclass and add corresponding
description.

Tried =sci-libs/rocBLAS-5.4.2, can compile successfully with amdgpu_targets_gfx1100 (but not tested on real GPU).
rocBLAS-5.4.2.ebuild is in https://github.com/gentoo/gentoo/pull/29319

The github PR for this patch is at
https://github.com/gentoo/gentoo/pull/29320

Closes: https://bugs.gentoo.org/891499
