test: remove rapidcheck integration and tests
Summary:
Whilst the property tests are interesting, ultimately rapidcheck integration in this repository has not gained much traction. We have a limited number of tests, and they are rarely (if ever) run.
Backport of core PR18514.
Test Plan:
Check there is no Cmake issue:
ninja all check
Return nothing:
git grep -i rapidcheck git grep -i property_based
