[CMake] Add pkgconfig and CMake config files for xpti and xptifw (#21599) (#21968) Cherry pick of c80095cec990c2d0b56bee02d7587ce41933c247 -------------------------------------------- We have some downstream code looking for `xpti`/`xptifw` directly, so provide CMake config files and pkgconfig files that will provide the information they need. Also set the `VERSION` target property so the generated libraries are versioned. For some reason setting the `project` version doesn't automatically do this. I tested the CMake config files on Linux and Win and the pkgconfig files on Linux (as we don't generate them for Win).
