mesa: rework viewport/scissor initialization code
The first time a context is bound to a drawable, the viewport and scissor
bounds are initialized to the buffer's size. This is actually a bit tricky.
A new _mesa_check_init_viewport() function is called in several places
to check if the viewport has been initialized. We also use a new
ctx->ViewportInitialized flag instead of the overloaded
ctx->FirstTimeCurrent flag.
