Fix cudf::stable_sorted_order for NaN and -NaN in FLOAT64 columns

[davidwendt]

Description

Fixes bug in cudf::stable_sorted_order when -NaN and NaN are in a FLOAT64 (double) columns.
The code was fixed by refactoring common code with cudf::sorted_order. This uses thrust sort functions to help align the behavior and keep results consistent.

New gtests were added to check for this case. Some test files were also updated per issue #11734
The new tests are at the bottom of sort_test.cpp and stable_sort_tests.cpp

This was found while working on #11729
The sorted-order functions are reused for many of the libcudf sort functions so this will help with the work in #11729
