dither: improve documentation

- `config.h`: Macros defining information about the way libplacebo was built,
including the version strings and compiled-in features/dependencies. Usually
does not need to be included directly. May be useful for feature tests.
- `dither.h`: Some helper functions for generating various noise and dithering
matrices. Might be useful for somebody else.
- `filters.h`: A collection of reusable reconstruction filter kernels, which
can be used for scaling. The generated weights arrays are semi-tailored to
the needs of libplacebo, but may be useful to somebody else regardless. Also
