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.
