sci-libs/caffe2: update dependencies to fix rocm flag

pytorch 2.3.0 introduced 2 new direct dependencies: hipBLASLt and aotriton.

pytorch uses hipBLASLt to perform gemm operation on datacenter AMD Instinct GPUs. For other GPUs pytorch fallbacks to hipBLAS.
caffe2-2.3.x ebuilds now contain a patch to optionally disable this dependency, when none AMDGPU_TARGETS="gfx90a gfx940 gfx941 gfx942" is used.

pytorch uses aotriton to perform FlashAttention operation.
caffe2-2.3.x ebuilds now contain a patch which fully disables aotriton dependency, as there is no such package yet.
Technically aotriton can be compiled (with minor patches), but I suggest to wait for next releases.
It is a massive burden, as it depends on forked triton and forked clang (merge with upstream is not expected anytime soon).
aotriton is usually distributed as a huge static (!) library (but in next release library will be shared).

Minor fixes added for compatibility with libc++ (used in experimental llvm Gentoo profile), however other ebuilds also require minor patches
(in other words: right now ROCm ecosystem can be compiled with libc++, but only by people with experience in C++).
