Create a new file property.

A file property represent a piece of information about a file that can be set during preprocessing. If the -output-metadata FILE command line option was passed to the driver, then it will output this information to the given file.

This mechanism is used to pass information gathered while preprocessing the file to the build system. For instance, this is used by ppx_inline_test to tell whether a file contains tests or not.

In the future we could also use this to directly compute the dependencies and pass them here, to avoid calling ocamldep separately.
