Fixed cache warmup of paths which contain back-slashes

From #8781

"
At this step in the warmup process there is a string replacement made, but paths with backslashes
are written into the cache file as something like `C:\\path\\to\\cache/pro_/...` but the str_replace
searches for the plain string `C:\path\to\cache/pro_/...`, which produces no matches.

The fix solves this by using var_export to escape the search (and replace) paths so they match the
format originally output into the cache file.

The `PropelTypeGuesser` did not match OneToMany relations properly. For example if you have a `Author` class with `Comments` attributes the guesser would guess "Comment" instead of "Comments".

I added some tests to ensure the non regression.

I'm not a big fan of this fix, but - at least - it works.

With this code, finally, Process does not behave the same at all on Windows and Linux.
This patch does not smells very good but it solves the random failing test issue (that produced at runtime too).

Actually, calling `proc_get_status` within the waiting loop introduced the bug.
So this PR reverts to the previous behavior (consider a process running as long as pipes give data). On Windows, this is not the same behavior as we're not using streams but file handles. Whereas the feof of a stream is detected when the other side closes, the feof of a file handle can be reached at any time. So, on Windows, `proc_get_status` is called (checking the feof of the file handle might be positive until the executable outputs something), and we consider a process running as long as the information returned says it's running.

We could think of decouple windows and linux logic in two separated objects, using the interfaces I introduced in #8753. This could bring much more readability and make the code more easy to understand.
