docs: Fix a few typos

There are small typos in:
- docs/runner.rst
- docs/usage.rst
- src/waitress/parser.py
- src/waitress/server.py
- tests/test_functional.py

Fixes:
- Should read `preceding` rather than `preceeding`.
- Should read `multiple` rather than `multipe`.
- Should read `descriptors` rather than `desctriptors`.
- Should read `descriptor` rather than `desctriptor`.
- Should read `attempt` rather than `atempt`.
- Should read `analogous` rather than `analagous`.
