TST: Use pytest-xdist

hypothesis tests become flaky with pytest-xdist due to timing issues
when initializing values to draw from. This change removes the separate
hypothesis profiles for ci and disables hypothesis deadlines by default.

The ci/ci-fast profiles are removed because the timing difference between
them are barely different when the tests are parallelized.
