Improve FindWayland.cmake

Diff: https://git.reviewboard.kde.org/r/116646/diff/


Testing
-------

Created a test CMakeLists.txt to call this, and played with various arguments to COMPONENTS and OPTIONAL_COMPONENTS, including when include files for certain components were removed from the system (so those components would not be found).  Everything worked as expected.


Thanks,

Alex Merry
