[sdflib] new port

[talregev]

• Changes comply with the maintainer guide.
• The name of the port matches an existing name for this component on https://repology.org/ if possible, and/or is strongly associated with that component on search engines.
• Optional dependencies are resolved in exactly one way. For example, if the component is built with CMake, all find_package calls are REQUIRED, are satisfied by vcpkg.json's declared dependencies, or disabled with CMAKE_DISABLE_FIND_PACKAGE_Xxx.
• The versioning scheme in vcpkg.json matches what upstream says.
• The license declaration in vcpkg.json matches what upstream says.
• The installed as the "copyright" file matches what upstream says.
• The source code of the component installed comes from an authoritative source.
• The generated "usage text" is accurate. See adding-usage for context.
• The version database is fixed by rerunning ./vcpkg x-add-version --all and committing the result.
• Only one version is in the new port's versions file.
• Only one version is added to each modified port's versions file.

I didn't find sdflib name nor the maintainer on https://repology.org/
I create a PR for the patch file:
UPC-ViRVIG/SdfLib#15

This port is needed for update mujoco:
https://github.com/google-deepmind/mujoco/blob/main/cmake/MujocoDependencies.cmake#L198

When testing usage, the following error occurs:

-- Configuring done (5.8s)
CMake Error at E:/sdflib/installed/x64-windows/share/sdflib/SdfLibConfig.cmake:60 (set_target_properties):
  The link interface of target "SdfLib::SdfLib" contains:

    glm::glm

  but the target was not found.  Possible reasons include:

    * There is a typo in the target name.
    * A find_package call is missing for an IMPORTED target.
    * An ALIAS target is missing.

@MonicaLiu0311
I added:

include(CMakeFindDependencyMacro)
find_dependency(glm CONFIG)
find_dependency(spdlog CONFIG)
find_dependency(cereal CONFIG)

Can you test the port again? Thank you for your review.

[MonicaLiu0311]

The usage test passed on x64-windows (header files found).

If the upstream does not export it, please add "unofficial-" before the config file.
