tidy-up: miscellaneous

- CMake/CurlTests.c: sync indent with rest of file and most of code.
- cmake: sync term in `_CURL_PREFILL` description with rest of code.
- curl_setup.h: document function relying on `_CRT_SECURE_NO_WARNINGS`.
- tests/http/scorecard.py: typo in message.
- 'Quiche' -> 'quiche'.
- fix comment and formatting nits.

Closes #22378
