Test CUDA in all supported Standard modes

[StephanTLavavej]

Currently, we test CUDA in only C++14 mode, because that's all that was available when we added this test coverage years ago:

STL/tests/std/tests/GH_000639_nvcc_include_all/env.lst

Lines 4 to 7 in a26f4ad

	PM_COMPILER="nvcc" PM_CL="--x cu -Xcompiler -Od,-EHsc,-nologo,-W4,-WX,-openmp"
	RUNALL_CROSSLIST
	PM_CL="-Xcompiler -MT"
	PM_CL="--debug -Xcompiler -MTd"

Since then, they've added support for C++17 and C++20. We should extend this test accordingly (after figuring out the right compiler options).
