[eventbus] Add new port

[motazmuhammad]

Fixes##41549

• 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.

@JonLiu1993 Now that all the test have passed, is the port ready for review? and/or approval?

[JonLiu1993]

Tested usage successfully by eventbus:x64-windows:

eventbus provides CMake targets:

  # this is heuristically generated, and may not be correct
  find_package(EventBus CONFIG REQUIRED)
  target_link_libraries(main PRIVATE Dexode::EventBus)

The portfile fetches the wrong revision for the claimed version.

@dg0yt the latest version would fail on windows there were some fixes added to address that in the commit referenced REF, and according to the maintainers guide, if a patch is in the upstream I should favor using it than patching the code myself, What should I do in this case?

To summarize, using v${VERSION} will fail

[dg0yt]

4689564c4c775456bfa0dfd976b4f48aca5f4d2a is older than, and included, in 3.1.2:
gelldur/EventBus@4689564

So this is just totally wrong. If the build fails with 3.1.2, check the actual error.
