Subject: cmake: allow disabling `RANDOM_FILE`
X-Git-Tag: curl-8_10_0~69

cmake: allow disabling `RANDOM_FILE`

`./configure` allows `--random-file=no`. Allow this with CMake too,
using `-DRANDOM_FILE=OFF` (other boolean values work too: no, false, 0,
case insensitive.)

Also disable `RANDOM_FILE` detection for Windows.

Closes #14743
