Enable multiconfig builds.
Fixes NVIDIA#1159. Also fixes or works around these issues: - WAR NVIDIA#1167: - Disable arches 53, 62, 72 for RDC-required tests, print warning - Error when ENABLE_RDC for tests/examples is set with a no-RDC arch. - Fixes NVIDIA#1168: Set RUN_SERIAL on OpenMP and TBB tests. - WAR ccache/ccache#598: nvcc flags `s/-Werror all-warnings/-Xcudafe --promote_warnings/g` - WAR NVIDIA#1174: remove warning promotion from tbb.cuda targets. - WAR NVIDIA#976: Add options to enable/disable tests, examples, header_tests: - THRUST_ENABLE_TESTING - THRUST_ENABLE_EXAMPLES - THRUST_ENABLE_HEADER_TESTING Summary: - Bump CMake requirement to 3.15 - Needed for CUDA_COMPILER_ID generator expression. - Removed workarounds for older CMake versions. - Removed warning flag specific to for C++98. - Dialects are now configured through target properties. Add new THRUST_CPP_DIALECT option for single config mode, and remove logic that modified CMAKE_CXX_STANDARD and CMAKE_CUDA_STANDARD. - Move testing related CMake code to `testing/CMakeLists.txt` - Move example related CMake code to `examples/CMakeLists.txt` - Move header testing related CMake code to `cmake/ThrustHeaderTesting.cmake` - Move CUDA configuration logic to `cmake/ThrustCUDAConfig.cmake`. - Explicitly `include(cmake/*.cmake)` files rather than searching CMAKE_MODULE_PATH -- we only want to use the ones in the repo. - Added ThrustMultiConfig.cmake - Handle MultiConfig (and single config) logic. - Added ThrustBuildTargetList.cmake - Builds the THRUST_TARGETS list, which contains one interface target for each enabled host/device/dialect configuration. - Added ThrustBuildCompilerTargets.cmake - Move warning flag, etc setup into it, bind compile interfaces to targets instead of global variables. - Renamed common_variables.cmake to ThrustCommonVariables.cmake - Removed THRUST_TREAT_FILE_AS_CXX - This worked by setting a cmake SOURCE_FILE property, which no longer works since multiconfig may build the same source file with both CXX and CUDA. - Instead, the `.cu` files are wrapped in a `.cpp` file that does nothing but include the `.cu` file. The `.cpp` files are then added to the CXX targets as sources. - See `cmake/ThrustUtilities.cmake` for implementation. - Fix bug in thrust-config.cmake where an internal var was not cached as expected.

# Thrust's tests, examples, etc.
8+

# - May be combined with thrust.compiler_interface when #1174 is fully resolved.
