Subject: [PATCH] [projectm-eval] Add new port (#38550)

This new overlay-port introduces the ProjectM Expression Evaluation
Library, which is a prerequisite for building the ProjectM Library. This
addition is to complement the PR #38535, which aims to address the
external dependency concern.

ProjectM: https://github.com/projectM-visualizer/projectm
ProjectM Eval: https://github.com/projectM-visualizer/projectm-eval

---
- [x] Changes comply with the [maintainer
guide](https://github.com/microsoft/vcpkg-docs/blob/main/vcpkg/contributing/maintainer-guide.md).
- [x] 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.
- [x] 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](https://cmake.org/cmake/help/latest/variable/CMAKE_DISABLE_FIND_PACKAGE_PackageName.html).
- [x] The versioning scheme in `vcpkg.json` matches what upstream says.
- [x] The license declaration in `vcpkg.json` matches what upstream
says.
- [x] The installed as the "copyright" file matches what upstream says.
- [x] The source code of the component installed comes from an
authoritative source.
- [x] The generated "usage text" is accurate. See
[adding-usage](https://github.com/microsoft/vcpkg-docs/blob/main/vcpkg/examples/adding-usage.md)
for context.
- [x] The version database is fixed by rerunning `./vcpkg x-add-version
--all` and committing the result.
- [x] Only one version is in the new port's versions file.
- [x] Only one version is added to each modified port's versions file.
