mesa: Make sure that imm draws are flushed before other draws execute.

The recent patch

    mesa: Remove FLUSH_VERTICES from VAO state changes.

    Pending draw calls on immediate mode or display list calls do
    not depend on changes of the VAO state. So, remove calls to
    FLUSH_VERTICES and flag _NEW_ARRAY as appropriate.

uncovered a problem that non immediate mode draw calls do only
flush outstanding immediate mode draws if FLUSH_UPDATE_CURRENT
is set in ctx->Driver.NeedFlush.
In that case, due to the sequence of _mesa_set_draw_vao commands
we could end up with the VAO from the FLUSH_VERTICES call set
into gl_context::Array._DrawVAO when the array draw is executed.
So the change pulls FLUSH_CURRENT out of _mesa_validate_* calls
into the array draw calls being validated.
The change introduces a new macro FLUSH_FOR_DRAW beside FLUSH_VERTICES
and FLUSH_CURRENT that flushes on changed current attributes as well
as on outstanding immediate mode draw calls. Use FLUSH_FOR_DRAW
in the non immediate mode draw code paths.
