Subject: winbuild: Use NMake batch-rules for compilation

- Invoke cl compiler once for each group of .c files.

This is significantly improves compilation time. For example in my
environment: 40 s --> 20 s.

Prior to this change cl was invoked per .c file.

Closes https://github.com/curl/curl/pull/9512
