[geo-utils] new port

[gistrec]

Describe the pull request

• What does your PR fix?

  Adds a new port for geo-utils — a header-only C++17 library for spherical (lat/lng) geometry: distance, bearing, polygon area, point-in-polygon, path proximity.
  License: Apache-2.0. No runtime dependencies.

• Which triplets are supported/not supported? Have you updated the CI baseline?

  Header-only, builds and installs cleanly on arm64-osx locally. Should work on all triplets the upstream CMake supports (Linux gcc/clang, macOS AppleClang, Windows MSVC — verified by upstream CI). No ci.baseline.txt changes needed.

• Does your PR follow the maintainer guide?

  Yes — license expression, homepage, version, vcpkg-cmake / vcpkg-cmake-config dependencies, copyright via vcpkg_install_copyright, no debug/lib leakage (header-only).

• If you have added/updated a port: Have you run ./vcpkg x-add-version --all and committed the result?

  Yes — versions/g-/geo-utils.json and versions/baseline.json updated.

• If you have added/updated a port: Have you added/updated a Versioning info?

  Yes.

Test plan

• Local install ./vcpkg install geo-utils succeeds on arm64-osx
• Post-build validation passes
• Heuristic CMake target detection: find_package(GeoUtils CONFIG REQUIRED) + geo::utils
• vcpkg CI on Linux/macOS/Windows

Unfortunately the name "geo-utils" in repology already refers to another component so I think we have to use the GitHubOrg-Repo form for this one.

I fixed these nitpicks and made that rename for you in gistrec#1

[BillyONeal]

We should set VCPKG_BUILD_TYPE to release to avoid needing this part.

Quoth GPT 5.4:

License / Installed Content Findings

• Finding: upstream attribution appears incomplete in the installed package metadata
  • Declared license: Apache-2.0
  • Observed installed content: packages\geo-utils_x64-windows\include\geo\detail\math.hpp, include\geo\latlng.hpp, include\geo\poly.hpp, include\geo\spherical.hpp
  • Evidence: those headers state Portions of this file are based on Google Maps Android Utils and name Copyright 2013 Google Inc.; upstream also ships a NOTICE file with that attribution:
    • buildtrees\geo-utils\src\v1.0.0-d48bd1e966.clean\include\geo\detail\math.hpp:1-12
    • buildtrees\geo-utils\src\v1.0.0-d48bd1e966.clean\NOTICE:1-5
  • Assessment: the SPDX license field Apache-2.0 still looks compatible, but the installed share\geo-utils\copyright contains only the Apache license text and does not carry the upstream NOTICE attribution. Since upstream includes a NOTICE file and the installed headers explicitly identify derived Google code, this should be preserved in the package copyright material.
