This was added in #10394 for both the hardware and software backends to work around an issue with Mario Kart Wii, Fortune Street, and Baten Kaitos. However, it seems like the software renderer handles blending well enough that we don't need this (and in any case, it's easy to change blending in the software renderer).
Some experimentation with #11387 (not pushed) showed that the software renderer's logic would also produce correct results on the hardware backends with this hack removed, but would require fbfetch (currently); if a better solution is found the hack can also be removed from the hardware backends.
The former is deprecated and pretty much all modern drivers
support VK_EXT_debug_utils.
Android drivers dont support it. On those drivers,
we use the implementation provided by the validation layers.

The Vulkan spec states: maxSets must be greater than 0
BindFramebuffer depends on the pipeline which might not be set yet.
That's why the framebuffer dirty flag exists in the first place.
I assume BindFramebuffer was called directly here, in order to handle
the texture state transitions necessary for DiscardResource.
The state is tracked anyway, so we can just issue those transitions there
too and defer binding the actual framebuffer.
Fixes an issue in Zelda Twilight Princess with EFB depth peeks.
Dolphin would bind a frame buffer which doesn't have an integer format
descriptor for the color target before binding the new pipeline.
So it would accidentally use the 0 descriptor.

GetGPUDescriptorHandleForHeapStart is invalid to call on a descriptor
