profiles/desc: add gfx950 for rocm-7.0.2

Browse Source 
This is initial change for ROCm-7.0.2 packages, followed by registration
of new targets in rocm.eclass.

Most of requests related to gfx115x (Strix / Strix Point) can be
solved only with ROCm-7.0.x (which was added to profiles/desc earlier,
but caused compilation failures). Examples:
https://bugs.gentoo.org/962820,
https://bugs.gentoo.org/962822

This release also adds support for gfx1200 (RDNA4) with few mid-segment
GPUs (https://en.wikipedia.org/wiki/Radeon_RX_9000_series), with <=16GB
of memory, but with native support of int8/int4 quantized computations
(RDNA4-only), which compensates on that.

The new gfx950 target - a flagship in AMD Instinct series (which
requires >64 of RAM to compile, see https://bugs.gentoo.org/960513,
so I can't even compile it on my main machine).
As for gfx1150, the code is still arriving to develop branches.
gfx940 and gfx941 were moved to "unofficial", but these devices should
be compatible with gfx942 code (as far as I know).

While ROCm-7 release was advertised as "Up to 3.8x Performance Uplift",
in reality performance improvements for consumer GPUs are negligible.
Maybe the comparison was done between old fp16 vs new quantized
int8/int4 (i. e. apples with oranges), which is obviously faster.

There are no LLVM changes (still custom version of llvm-20), the release
looks mostly incremental (apart from int8/int4 features, added only for
RDNA4-capable GPUs). There is an internal restructuration, most of the
packages changed HOMEPAGE: hipBLAS, hipBLASLt , hipCUB, hipFFT, hipRAND,
hipSPARSE, hipSPARSELt, MIOpen, rocBLAS, rocFFT, rocPRIM, rocRAND,
rocSPARSE, rocThrust, and Tensile were moved to
https://github.com/ROCm/rocm-libraries monorepository, while some others
were moved to https://github.com/ROCm/rocm-systems. SRC_URI are still
the same, as ROCm continues to publish them. Downloading the whole
monorepo (471 mb tar.gz) is just bad user experience, so we might at
least defer it.
