cmake: add `find_package()` missing from `USE_MSH3` option

The original patch added the Find module and CMake option. But the logic
missed a `find_package(MSH3)` call to use that Find module, leaving the
referenced `MSH3_INCLUDE_DIRS`, `MSH3_LIBRARIES` variables undefined.

Blind fix.

Closes #14609
