Move equivalence fuzz testing to fuzz test binary

[alamb]

Which issue does this PR close?

Part of #12700

Rationale for this change

These two tests are fuzz tests and they take 3 orders of magnitude more time to run than the rest of the tests in datafusion-physical-expr

You can see this with

cargo nextest run -p datafusion-physical-expr --lib

        PASS [   0.004s] datafusion-physical-expr window::window_expr::tests::test_is_row_ahead
        PASS [   3.604s] datafusion-physical-expr equivalence::ordering::tests::test_ordering_satisfy_with_equivalence_complex_random
        PASS [   4.350s] datafusion-physical-expr equivalence::properties::tests::test_find_longest_permutation_random
        PASS [  15.111s] datafusion-physical-expr equivalence::projection::tests::ordering_satisfy_after_projection_random

Let's move the fuzz testing to the fuzz test binary to make normal testing faster
