panfrost: Update supported formats
Much of the format selection code was inherited from softpipe (!) of all
places, and a lot of it is accordingly cruft. Later if-elses were added
in random places to workaround missing formats at various points in
history. Clean up some of this.
Theoretically, any format we can texture from we can also render to. In
practice, there are a few corner cases that we need to disable
explicitly.
For one, we do have to restrict SCANOUT formats to workaround
buggy apps (in particular, dEQP which with --deqp-surface-type=window
under Weston will end up with RGB10_A2 and complain about low alpha
precision). Just be clearer about how/why.
Also, RGB5_A1 support is still broken; let's not worry about that quite
yet.

panfrost/midgard: Handle pure int formats
I'm not sure I'm totally comfortable with this, but conceptually neither
float nor pure-int formats require any format conversion, except size
conversion. Going from a shaderable format (fp32 or i16, for instance)
into a blendable format (fp16) is a separate question, one we can defer
momentarily while we're not interested in actually blending.
As an aside, I'd be fascinated by an integer-based blending
implementation.

panfrost/midgard: Implement integer downsize ops
Oh, dear. No turning back now.
We begin implementing non-32-bit types, using downsizing integer type
conversions as the initial instructions. We implement them naively as
type-converting moves; substantially more efficient operation is
possible by copypropping the type conversion modifier, but this
optimization is not implemented here.
Size converting modifiers on Midgard allow an instruction to write to a
destination 1/2 the size, or to read from a source 1/2 the size. If we
need an extreme conversion (32-bit to 8-bit, for instance), multiple
type converting ops are chained together, which here is handled via an
algebraic pass.
