support for the WebP image format (tdf#114532)

This commit implements a WebP reader and writer for both lossless
and lossy WebP, export dialog options for selecting lossless/lossy
and quality for lossy, and various internal support for the format.

Since writing WebP to e.g. ODT documents would make those images
unreadable by previous versions with no WebP support, support
for that is explicitly disabled in GraphicFilter, to be enabled
somewhen later.
