[portmidi] Fix dependency searching (#30265)

* [portmidi] Search for Threads in the CMake config.

Without this, consuming the library in CMake would result in the
following error:

The link interface of target "PortMidi::portmidi" contains:

  Threads::Threads

but the target was not found.

* [portmidi] Cleanup portfile.

- Copy pdbs
- Use vcpkg_install_copyright
- Use ${VERSION}

* [portmidi] Install a usage file.

* [portmidi] Bump port-version.

* [portmidi] Update baseline.
