hvif2png: allow larger sizes.

What if I need some high resolution rendering of icons?

Also fix the error message for out of range/unparsable sizes that would
show "-s" as the problematic size.

hvif2png: Input file reading fix, file magic check

* Fix an infinite loop on reading a larger file.
* Check hvif magic number

Ticket #12207.

hvif2png: Fix closing of streams

* h2p_close_state():
- Don't close stdin/stdout.
- Set in/out to NULL to prevent accidental double closing.
* h2p_open_streams(): Simplify closing on error. No need for
fclose_quietly().

hvif2png: Coding style cleanup

Add build tool to render hvif icon files as png
