Deactivate PROJ's test building in the Superbuild

Summary

By default the PROJ CMake configure has the PROJ_TESTS option enabled, building PROJ tests. This MR disables this option.

Rationale

Closes #2113 (closed)

Implementation Details

Classes and files

• SuperBuild/CMake/External_proj.cmake : add option -DPROJ_TESTS:BOOL=OFF

Additional notes

Starting with PROJ 7.0, the PROJ_TESTS option has been renamed into BUILD_TESTING. For now, we use PROJ 6.2. But the day we update to PROJ 7+, we will need to update this file.
