addons: consume ggml-speech 2026-06-02 (whisper / tts-ggml / parakeet, QVAC-18993) (#2393)

* addons: overlay-validate ggml-speech 2026-06-02 consumer ports (QVAC-18993)

Adds vcpkg overlay ports into the whisper, tts-ggml, and parakeet addons to
validate registry PR tetherto/qvac-registry-vcpkg#179 before it merges:

  - ggml-speech       2026-06-02#0  (published via registry #178)
  - whisper-cpp       1.8.5#1       (requires ggml-speech 2026-06-02)
  - tts-cpp           2026-06-02#1  (requires ggml-speech 2026-06-02)
  - parakeet-cpp      2026-05-26#2  (requires ggml-speech 2026-06-02)

Overlays bypass the version DB, so the default-registry baselines and the
addon version pins are intentionally left unchanged. Once #179 merges, a
follow-up commit removes these overlays and bumps the depended-on versions in
each addon's vcpkg.json (no baseline bump).

parakeet's .gitignore excludes *.cmake, so the overlay portfile.cmake files
were force-added.

* addons: route spirv-headers to microsoft registry for tts-ggml + parakeet

ggml-speech 2026-06-02's vulkan feature depends on spirv-headers (>=1.4.341.0),
which only exists in the microsoft/vcpkg registry. whisper's config already
routed it, but tts-ggml (had vulkan/headers/loader only) and parakeet (gtest+
zlib only) did not, so vcpkg fell through to the tetherto default registry and
failed: "the baseline does not contain an entry for port spirv-headers".

Verified locally on x64-linux: both addons now resolve spirv-headers@1.4.341.0
from microsoft HEAD and build ggml-speech[vulkan] + their consumer port.

* addons: consume ggml-speech 2026-06-02 via registry #179 (remove overlays, pin versions)

Registry PR tetherto/qvac-registry-vcpkg#179 merged, publishing whisper-cpp
1.8.5#1, tts-cpp 2026-06-02#1, parakeet-cpp 2026-05-26#2 -- each requiring
ggml-speech 2026-06-02 (Adreno backend selection from qvac-ext-ggml#18).

Finalizes the addon side:
  - removes the validation overlay ports
  - bumps the depended-on version in each addon (NO baseline change):
      whisper:  override whisper-cpp   -> 1.8.5#1
      tts-ggml: version>= tts-cpp      -> 2026-06-02#1
      parakeet: version>= parakeet-cpp -> 2026-05-26#2
  - keeps spirv-headers routed to microsoft (ggml-speech 2026-06-02's vulkan
    feature requires it) for tts-ggml + parakeet

Verified locally on x64-linux: all three resolve the new versions + ggml-speech
2026-06-02 + spirv-headers 1.4.341.0 from the merged registry with default-registry
baselines unchanged (a9d7e924 / 74d2dfd0).
