Re-org of st_create_framebuffer() and renderbuffer format selection.

st_create_framebuffer() now takes pipe_formats for the color, depth, stencil
buffers.
This avoids a round-about chain of calls to pipe->is_format_supported() for
window renderbuffers (their format never changes).
Renderbuffer format selection code in st_format.c is simpler now too.
