app-accessibility/whisper-cpp: drop 1.8.5, 1.8.6

Retention: keep the last two (1.9.0, 1.9.1) plus the last of the
previous minor series (1.8.7) for rollback. 1.8.5 and 1.8.6 are
redundant.

app-accessibility/whisper-cpp: set GGML_BLAS_VENDOR for USE=blas (backport)

The 1.9.1 ebuild gained an explicit -DGGML_BLAS_VENDOR=OpenBLAS for
USE=blas; the same bug is present in every other version. Each bundled
ggml defaults BLA_VENDOR to "Generic" on Linux, so CMake's FindBLAS
resolves the Fortran-only libblas.so (no cblas_sgemm) and the ggml-blas
backend fails to link. Backport the same gated fix to the retained
versions. Verified on 1.8.7 (oldest retained, most divergent ggml):
USE=blas now resolves /usr/lib64/libopenblas.so and libggml-blas.so
links and ldd's to libopenblas; 1.9.0 ships the identical ggml BLAS
CMake as 1.9.1. Gated on USE=blas; default builds are unchanged.

app-accessibility/whisper-cpp: set GGML_BLAS_VENDOR for USE=blas

With USE=blas the ebuild passed only -DGGML_BLAS=yes, so CMake's FindBLAS
resolved the generic Fortran libblas.so, which lacks the C interface
(cblas_sgemm) that the ggml-blas backend calls — the build failed at link
with an undefined reference. The ebuild already depends on sci-libs/openblas,
which ships cblas, so set -DGGML_BLAS_VENDOR=OpenBLAS to make FindBLAS
select it. Gated on USE=blas; the default build is unchanged.

app-accessibility/whisper-cpp: generalize CUDA host-compiler comment

Drop host-specific wording from the CUDAHOSTCXX rationale comment; the
dated verification note and the gcc>15 pin reason are kept.

app-accessibility/whisper-cpp: add 1.8.6

Adopts the new upstream option name WHISPER_COMMON_FFMPEG; the legacy
WHISPER_FFMPEG knob remains a deprecated alias for now, but tracking
the canonical name keeps the warning out of the build log and matches
the example/common refactor (examples/CMakeLists.txt no longer
references WHISPER_FFMPEG).

app-accessibility/whisper-cpp: new package, add 1.8.4 and 9999

Forked from guru; fixes vs. upstream:
- -DGGML_CUBLAS (silently ignored) → -DGGML_CUDA (verified 2026-05-14)
- BDEPEND shaderc gated on vulkan? (glslc only needed in ggml-vulkan backend)
- -DGGML_NATIVE=OFF to prevent -march=native injection; with
GGML_NATIVE_DEFAULT=ON and GGML_NATIVE=OFF, ggml's hand-optimised
AVX2/FMA/F16C kernels compile via INS_ENB=ON
- -DGGML_CCACHE=OFF in the sandbox
- -DWHISPER_BUILD_TESTS=OFF (tests require model files not in tarball)
- CMAKE_CUDA_HOST_COMPILER pinned to g++-15 when cuda USE is set
(CUDA 13.x nvcc rejects gcc>15; verified 2026-05-14)
