Film grain support adds a huge amount of overhead to the H264Context

This introduces a --disable-h264-film-grain option which makes
these fields optional and reduces the H264Context size from
851808 bytes to 53444 bytes.

Note: I'm not sure this is the right way to go about making this optional,
please
let me know if there's a better way.

The proper name for the option and define should be H274, or simply
film_grain if you're also including AV1FG in it.
I'm not against a change like this, but it needs to be thorough like we
did with iamfenc and iamfdec, and there's more code handling film grain
in other modules.
Not sure what Niklas thinks.
