st/vega: Refactor blend shaders.

Add a helper function, blend_generic, that supports all blend modes and
per-channel alpha.  Make other blend generators a wrapper to it.

Both the old and new code expects premultiplied colors, yet the input is
non-premultiplied.  Per-channel alpha is also not used for stencil
image.  They still need to be fixed.
