CMake: Add locator filter to open CMake target definitions

Add a "cmo" filter to the locator that will open the CMake target
definition in the editor.

Note that this is based on the target data extracted from cmake. For
tealeaf-reader and server-mode this information is guessed based on
the targets source directory (plus CMakeLists.txt). These modes will
just open that file.

For fileapi the information is accurate and based on the backtrace
that comes with the target information. "cmo" will open the exact
file/line from the backtrace here.
