Add option to enable all supported standards in for multiconfig.

[alliepiper]

The THRUST_MULTICONFIG_ENABLE_DIALECT_ALL option will turn on all
dialects supported by the configured CXX / CUDA compilers.

Fixes #1321.

[alliepiper]

@brycelelbach Would this be a suitable implementation of #1321 for your needs? It enables all supported dialects, not just the latest. I can still add a mode that just enables the latest if needed.

I'll add this logic to CUB once this PR is approved.

This doesn't appear to work with NVC++. When building with this branch:

This can be reproduced by building with ci/local/build.bash -i gpuci/cccl:nvhpc20.9-devel-ubuntu20.04-nvcxx20.9.

[brycelelbach]

Also, can this PR update gpuCI to use this new option? The three "coverage plans" in ci/common/build.bash will need to be updated to use this instead of hardcoding specific C++ dialects.

[alliepiper]

Per our discussion today:

• Also add a LATEST option (only latest, no other dialects)
• Implement for CUB, too.

[alliepiper]

run tests

[alliepiper]

• Added a LATEST option
• Updated the gpuCI scripts to use either ALL or LATEST dialects
• Verified that the new options are propagated to CUB when building CUB targets.

gpuCI is failing now, apparently calling enable_language from a function works on windows, but not on linux. I'll have to refactor this a bit more before it'll be ready.

Rewrote the dialect detection to check cmake properties instead of running try_compiles.
