Refactor Ceres threading option configuration. - Previously we had separate variables for each of the threading backends, each of which were made mutually exclusive via cmake_dependent_option(). This has unfortunate side-effects when trying to disable options if they are not currently enabled, in which case they are not defined. - As all the threading options are mutually exclusive, this replaces all threading option variables with a single variable: CERES_THREADS, which is constrained to take the value of only the available threading backends.
