Address Sanitizer reported two memory leaks because of
fmt not being freed in wlr_drm_format_set_copy.
This commit fixes the memory leak by removing the
allocation to the heap. The struct is allocated to the
stack anyway.
This is implemented by a two-subpass rendering scheme; the first
subpass draws (and blends) onto a linear R16G16B16A16_SFLOAT buffer,
while the second subpass performs linear->srgb conversion, writing
onto the actual output buffer.
This fixes the following validation errors when shutting down Sway:

Remove debug logs when a texture is created, since this happens
pretty often. Use drmGetFormatName() and drmGetFormatModifierName()
to log DRM formats and modifiers.
This ensures that the pool sizes grow exponentially, making the number
of pools needed logarithmic in the number of descriptors, instead of
linear. Since the first pool's size is 256, this change only has an
effect when the compositor creates a large number of textures.
The Wayland, X11 and headless backends don't really care about the
cursor size. We were picking a size identical to the texture size
in that case. This is incorrect for LoDPI cursor textures on HiDPI
outputs: in that case, we need to scale up the cursor texture.
Fixes the cursor being chopped off under the Wayland backend with
scale > 1.
Goals:
- Extensibility: we need to be able to add new params to the calls
to render a texture/rect. For instance we'll need to add fences to
the render texture operation for explicit sync purposes.
- No implicit state: no more bind_buffer, begin, end.
- No matrices: these hurt Pixman and we don't need them.
- Clip regions for optimized damage repainting.

Add a src_box state field. Use the SRC_* KMS props in the DRM
backend, reject the layers in the Wayland backend (for now, we can
support it later via viewporter).
